Portfolio Turnover [Text Block]

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 62% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests primarily in equity securities from developed countries included in the Morgan Stanley Capital International (MSCI) Europe, Australasia and Far East (EAFE) Value Index (net of foreign withholding taxes), which is the Fund’s benchmark. The Fund typically does not invest in U.S. companies.

Equity securities in which the Fund invests are common stocks, preferred stocks, convertible securities, depositary receipts, rights and warrants to buy common stocks and privately placed securities.

The Fund’s sector weightings generally approximate those of the MSCI EAFE Value Index, although the Fund does not seek to mirror the index in its choice of individual securities. In choosing stocks, the Fund emphasizes those that are ranked as undervalued according to the proprietary research of the adviser while underweighting or avoiding those that appear overvalued.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser employs a process that combines fundamental research for identifying portfolio securities and currency management decisions.

Various models are used to quantify the adviser’s fundamental stock research, producing a ranking of companies in each industry group according to their relative value. The Fund’s management team then buys and sells stocks, using the research and valuation rankings as well as its assessment of other factors, including:

• value characteristics such as low price-to-book and price-to-earnings ratios;

• catalysts that could trigger a change in a stock’s price;

• potential reward compared to potential risk; and

• temporary mispricings caused by market overreactions.

The Fund has access to the adviser’s currency specialists in determining the extent and nature of the Fund’s exposure to various foreign currencies.

The Fund may invest a substantial part of its assets in just one region or country.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Value Investing Risk. A value stock may decrease in price or may not increase in price as anticipated by the adviser if other investors fail to recognize the company’s value or the factors that the adviser believes will cause the stock price to increase do not occur.

Geographic Focus Risk. The Fund may focus its investments in a region or small group of countries. As a result, the Fund’s performance may be subject to greater volatility than a more geographically diversified fund.

Depositary Receipt Risk. The Fund’s investments may take the form of depositary receipts, including unsponsored depositary receipts. Unsponsored depositary receipts may not provide as much information about the underlying issuer and may not carry the same voting privileges as sponsored depositary receipts. Unsponsored depositary receipts are issued by one or more depositaries in response to market demand, but without a formal agreement with the company that issues the underlying securities.

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

To the extent that the Fund hedges its currency exposure, it may reduce the effects of currency fluctuations. The Fund may also hedge from one foreign currency to another. However, the Fund does not typically use this hedging strategy for its emerging markets currency exposure.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R2 Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Morgan Stanley Capital International (MSCI), Europe, Australasia and Far East (EAFE) Value Index (net of foreign withholding taxes) and the Lipper International Large-Cap Value Funds Average, an average based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper average includes the expenses of the mutual funds included in the average. The performance of Class R2 Shares is based on the performance of Class A Shares prior to the inception of Class R2 Shares. The actual returns of Class R2 Shares would have been lower than shown because Class R2 Shares have higher expenses than Class A Shares. The performance for Class R6 Shares is based on the performance of Institutional Class Shares prior to the inception of the Class R6 Shares. The actual returns of the Class R6 Shares would have been different than those shown because Institutional Class Shares have different expenses than Class R6 Shares. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund’s assets are invested primarily in equity securities of companies from developed countries other than the U.S. The Fund’s assets also may be invested, to a limited extent, in equity securities of companies from emerging markets. Developed countries include Australia, Canada, Japan, New Zealand, Hong Kong, the United Kingdom and most of the countries of Western Europe; emerging markets include most of the other countries in the world.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest.

The Fund may utilize currency forwards to manage currency exposure of its foreign investments relative to its benchmark. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser adheres to a disciplined process for stock selection and portfolio construction. A proprietary multifactor model is used to quantitatively rank securities in the Fund’s investment universe on the basis of value and growth factors. Value is measured by valuation multiples, while momentum is captured by factors such as relative price strength and earnings revisions. Securities held in the Fund that have become over-valued and/or whose growth signals have deteriorated materially may be sold. Securities that are sold are generally replaced with the most attractive securities, on the basis of the adviser’s disciplined investment process.

The portfolio construction process controls for sector and industry weights, number of stocks held, and position size. Risk or factor exposures are actively managed through portfolio construction.

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, Expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

High Portfolio Turnover Risk. The Fund will likely engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Institutional Shares | JPMorgan International Value Fund

JPMorgan International Value Fund

Class/Ticker: Institutional/JNUSX

What is the goal of the Fund?

The Fund seeks to provide high total return from a portfolio of foreign company equity securities.

Fees and Expenses of the Fund

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.

ANNUAL FUND OPERATING EXPENSES
(Expenses that you pay each year as a percentage of the
value of your investment)

Annual Fund Operating Expenses		Institutional Shares JPMorgan International Value Fund Institutional Class
Management Fees		0.60%
Distribution (Rule 12b-1) Fees		none
Other Expenses		0.37%
Shareholder Service Fees		0.10%
Remainder of Other Expenses		0.27%
Total Annual Fund Operating Expenses		0.97%
Fee Waivers and Expense Reimbursements	[1]	(0.02%)
Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements	[1]	0.95%

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the table through 2/28/14 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR
COST WOULD BE:

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
Institutional Shares JPMorgan International Value Fund INSTITUTIONAL CLASS SHARES	97	307	534	1,188

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR
COST WOULD BE:

Expense Example, No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
Institutional Shares JPMorgan International Value Fund INSTITUTIONAL CLASS SHARES	97	307	534	1,188

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 62% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund invests primarily in equity securities from developed countries included in the Morgan Stanley Capital International (MSCI) Europe, Australasia and Far East (EAFE) Value Index (net of foreign withholding taxes), which is the Fund’s benchmark. The Fund typically does not invest in U.S. companies.

Equity securities in which the Fund invests are common stocks, preferred stocks, convertible securities, depositary receipts, rights and warrants to buy common stocks and privately placed securities.

The Fund’s sector weightings generally approximate those of the MSCI EAFE Value Index, although the Fund does not seek to mirror the index in its choice of individual securities. In choosing stocks, the Fund emphasizes those that are ranked as undervalued according to the proprietary research of the adviser while underweighting or avoiding those that appear overvalued.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser employs a process that combines fundamental research for identifying portfolio securities and currency management decisions.

Various models are used to quantify the adviser’s fundamental stock research, producing a ranking of companies in each industry group according to their relative value. The Fund’s management team then buys and sells stocks, using the research and valuation rankings as well as its assessment of other factors, including:

• value characteristics such as low price-to-book and price-to-earnings ratios;

• catalysts that could trigger a change in a stock’s price;

• potential reward compared to potential risk; and

• temporary mispricings caused by market overreactions.

The Fund has access to the adviser’s currency specialists in determining the extent and nature of the Fund’s exposure to various foreign currencies.

The Fund may invest a substantial part of its assets in just one region or country.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Value Investing Risk. A value stock may decrease in price or may not increase in price as anticipated by the adviser if other investors fail to recognize the company’s value or the factors that the adviser believes will cause the stock price to increase do not occur.

Geographic Focus Risk. The Fund may focus its investments in a region or small group of countries. As a result, the Fund’s performance may be subject to greater volatility than a more geographically diversified fund.

Depositary Receipt Risk. The Fund’s investments may take the form of depositary receipts, including unsponsored depositary receipts. Unsponsored depositary receipts may not provide as much information about the underlying issuer and may not carry the same voting privileges as sponsored depositary receipts. Unsponsored depositary receipts are issued by one or more depositaries in response to market demand, but without a formal agreement with the company that issues the underlying securities.

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

To the extent that the Fund hedges its currency exposure, it may reduce the effects of currency fluctuations. The Fund may also hedge from one foreign currency to another. However, the Fund does not typically use this hedging strategy for its emerging markets currency exposure.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund will invest at least 80% of the value of its Assets in equity securities of Indian companies or instruments that have similar economic characteristics. “Assets” means net assets, plus the amount of borrowings for investment purposes. An Indian company is any company: that is organized under the laws of, or has a principal office in India; the principal securities market for which is India; that derives at least 50% of its total revenues or profits from goods that are produced or sold, investments made, or services performed in India; or at least 50% of the assets of which are located in India.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest. The Fund may from time to time hedge a portion of its foreign currency exposure into the U.S. dollar. The Fund is not constrained by capitalization or style limits.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: The Fund is managed by the sub-adviser using an active style of portfolio management which focuses on stock selection conducted by experienced country specialists. The subadviser employs a dedicated team of India specialists, located both within and outside India.

In managing the Fund, the sub-adviser seeks to add value primarily through stock selection decisions. In evaluating investment opportunities, the sub-adviser considers several criteria, including growth prospects, valuation, productive use of capital, competitive positioning, and corporate governance.

Indian country specialists are encouraged to visit a wide range of companies across a variety of sectors, and it is from these company visits that the sub-adviser can make qualitative assessments of the relative growth prospects of the companies concerned and their strategies to create shareholder value. The sub-adviser analyzes industries in which companies operate, the competitive landscape as well as the management strategy to enhance competitive advantage and returns. As part of the investment process, the country specialists not only meet with some of the companies which fall outside their core stock coverage, but they also meet with some of their competitors, distributors, suppliers and other stakeholders in order to obtain a complete analysis of the industry/company and other investment opportunities.

The portfolio managers are responsible for implementing the recommendations of the country specialists, who make their recommendations based on their extensive research. The sub-adviser prefers to construct a concentrated portfolio, thereby facilitating greater knowledge of the underlying holdings. The Fund also has access to the adviser’s team of global fund managers who may add insight at the sectoral, economic or other levels.

The Fund will sell securities if the sub-adviser believes the issuer of such securities no longer meets certain growth criteria, if certain political and economic events occur, or if it believes that more attractive opportunities are available.

The Fund is non-diversified.

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Indian Market Risk. Investments in India can be considered speculative, and therefore may offer higher potential for losses. Political and economic structures in India generally lack the social, political and economic stability of more developed nations. Share prices of Indian companies tend to be volatile, can be subject to currency exchange fluctuations and can lack liquidity. The stock markets in India are undergoing a period of growth and change, which may result in trading or price volatility and difficulties in the settlement and recording of transactions, and in interpreting and applying the relevant laws and regulations. The risk of loss may be increased because Indian issuers are not subject to the extensive accounting, auditing and financial reporting standards and practices which are applicable in the United States. There is also a lower level of regulation and monitoring of the Indian securities market and its participants than in other more developed markets.

Because the Fund concentrates in a single region of the world, the Fund’s performance may be more volatile than that of a fund that invests globally. If Indian securities fall out of favor, it may cause the Fund to underperform funds that do not concentrate in a single region of the world.

Smaller Cap Company Risk. Investments in securities of smaller companies may be riskier and more volatile and vulnerable to economic, market and industry changes than securities of larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

Non-Diversified Fund Risk. Since the Fund is nondiversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased concentration in fewer issuers may result in the Fund’s shares being more sensitive to economic results of those issuing the securities.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Institutional Shares | JPMorgan Intrepid International Fund

JPMorgan Intrepid International Fund

Class/Ticker: Institutional/JFTIX

What is the goal of the Fund?

The Fund seeks to maximize long-term capital growth by investing primarily in equity securities in developed markets outside the U.S.

Fees and Expenses of the Fund

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.

ANNUAL FUND OPERATING EXPENSES
(Expenses that you pay each year as a percentage of the value
of your investment)

Annual Fund Operating Expenses		Institutional Shares JPMorgan Intrepid International Fund Institutional Class
Management Fees		0.85%
Distribution (Rule 12b-1) Fees		none
Other Expenses		0.36%
Shareholder Service Fees		0.10%
Remainder of Other Expenses		0.26%
Acquired Fund Fees and Expenses		0.01%
Total Annual Fund Operating Expenses		1.22%
Fee Waivers and Expense Reimbursements	[1]	(0.21%)
Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements	[1]	1.01%

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the table through 2/28/14 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR
COST WOULD BE:

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
Institutional Shares JPMorgan Intrepid International Fund INSTITUTIONAL CLASS SHARES	103	366	650	1,459

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR
COST WOULD BE:

Expense Example, No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
Institutional Shares JPMorgan Intrepid International Fund INSTITUTIONAL CLASS SHARES	103	366	650	1,459

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 46% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund’s assets are invested primarily in equity securities of companies from developed countries other than the U.S. The Fund’s assets also may be invested, to a limited extent, in equity securities of companies from emerging markets. Developed countries include Australia, Canada, Japan, New Zealand, Hong Kong, the United Kingdom and most of the countries of Western Europe; emerging markets include most of the other countries in the world.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest.

The Fund may utilize currency forwards to manage currency exposure of its foreign investments relative to its benchmark. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser adheres to a disciplined process for stock selection and portfolio construction. A proprietary multifactor model is used to quantitatively rank securities in the Fund’s investment universe on the basis of value and growth factors. Value is measured by valuation multiples, while momentum is captured by factors such as relative price strength and earnings revisions. Securities held in the Fund that have become over-valued and/or whose growth signals have deteriorated materially may be sold. Securities that are sold are generally replaced with the most attractive securities, on the basis of the adviser’s disciplined investment process.

The portfolio construction process controls for sector and industry weights, number of stocks held, and position size. Risk or factor exposures are actively managed through portfolio construction.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, Expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

High Portfolio Turnover Risk. The Fund will likely engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Institutional Class Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Morgan Stanley Capital International (MSCI) Europe, Australasia and Far East (EAFE) Index (net of foreign withholding taxes) and the Lipper International Multi-Cap Core Funds Index , an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund’s assets are invested primarily in equity securities of companies from developed countries other than the U.S. The Fund’s assets also may be invested, to a limited extent, in equity securities of companies from emerging markets. Developed countries include Australia, Canada, Japan, New Zealand, Hong Kong, the United Kingdom and most of the countries of Western Europe; emerging markets include most of the other countries in the world.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest.

The Fund may utilize currency forwards to manage currency exposure of its foreign investments relative to its benchmark. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser adheres to a disciplined process for stock selection and portfolio construction. A proprietary multifactor model is used to quantitatively rank securities in the Fund’s investment universe on the basis of value and growth factors. Value is measured by valuation multiples, while momentum is captured by factors such as relative price strength and earnings revisions. Securities held in the Fund that have become over-valued and/or whose growth signals have deteriorated materially may be sold. Securities that are sold are generally replaced with the most attractive securities, on the basis of the adviser’s disciplined investment process.

The portfolio construction process controls for sector and industry weights, number of stocks held, and position size. Risk or factor exposures are actively managed through portfolio construction.

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

High Portfolio Turnover Risk. The Fund will likely engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

The Fund’s Past Performance

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Morgan Stanley Capital International (MSCI) Europe, Australasia and Far East (EAFE) Index (net of foreign withholding taxes) and the Lipper International Multi-Cap Core Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance of Class C Shares is based on the performance of Class A Shares prior to the inception of Class C Shares. Actual returns of Class C Shares would have been lower than those shown because Class C Shares have higher expenses than Class A Shares. The performance of Select Class Shares is based on the performance of Institutional Class Shares prior to the inception of Select Class Shares. Actual returns of Select Class Shares would have been lower than those shown because Select Class Shares have higher expenses than Institutional Class Shares. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111. The performance figures in the bar chart do not reflect any deduction for the front-end sales charge, which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund will invest at least 80% of the value of its Assets in equity securities of Russian companies or instruments that have similar economic  characteristics. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund may, to a lesser extent, invest in equity securities of companies in the former Soviet Union countries other than Russia, or instruments that have similar economic characteristics. A Russian company is any company: that is organized under the laws of, or has a principal office in Russia; the principal securities market for which is Russia; that derives at least 50% of its total revenues or profits from goods that are produced or sold, investments made, or services performed in Russia; or at least 50% of the assets of which are located in Russia.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest. The Fund may from time to time hedge a portion of its foreign currency exposure into the U.S. dollar.

Investment Process: In managing the Fund, the adviser will use an active style of portfolio management which focuses on bottom-up stock selection conducted by experienced country specialists.

In managing the Fund, the adviser seeks to add value primarily through stock selection decisions. The adviser places a strong emphasis on bottom-up stock research conducted by country specialists. Macro research is used as a framework for this bottom-up analysis. The investment process is characterized by identifying and purchasing securities issued by high quality companies with sustainable earnings growth on attractive valuations, and avoiding overvalued stocks and markets. The adviser prefers to construct a concentrated portfolio, thereby facilitating greater knowledge of the underlying holdings.

The Fund will sell securities if the adviser believes the issuer of such securities no longer meets certain growth criteria, if certain political and economic events occur, or if the adviser believes that more attractive opportunities are available.

The Fund is non-diversified.

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Russian Market Risk. Investing in Russian securities is highly speculative and involves significant risks and special considerations. Since the breakup of the Soviet Union in 1991, Russia continues to experience dramatic political and social change. Though Russia has been transitioning from a centrally controlled command system to a more market-oriented democratic model, recent political developments have trended back to high government involvement and centralized control in some industries, such as Russia’s oil and gas industries. The Russian securities markets are substantially smaller, less liquid and more volatile than the securities markets in the U.S., with a few issuers representing a large percentage of market capitalization and trading volume.

The Fund may be affected unfavorably by political developments, social instability, changes in government policies, and other political and economic developments. There is the potential for expropriation, dilution, devaluation, default or excessive taxation by the Russian government or any of its agencies or political subdivisions with respect to investments in Russian securities by or for the benefit of foreign entities. The Russian economy is heavily dependent upon the export of commodities  including most industrial metals, forestry products, oil and gas. Accordingly, it is strongly affected by international commodity prices and global demand for these products. Furthermore, it is possible that the Fund’s ownership rights could be lost through fraud or negligence because ownership of shares in Russian companies is recorded by the companies themselves and by registrars instead of through a central registration system. Since the Russian banking institutions and registrars are not guaranteed by the state, the Fund may not be able to pursue claims on behalf of the Fund’s shareholders.

Because the Fund concentrates in a single region of the world, the Fund’s performance may be more volatile than that of a fund that invests globally. If Russian securities fall out of favor, it may cause the Fund to underperform funds that do not concentrate in a single region of the world.

Smaller Cap Company Risk. Investments in securities of smaller companies may be riskier and more volatile and vulnerable to economic, market and industry changes than securities of larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

Derivatives Risk. Derivatives may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Non-Diversified Fund Risk. Since the Fund is nondiversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased concentration in fewer issuers may result in the Fund’s shares being more sensitive to economic results of those issuing the securities.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

This section provides some indication of the risks of investing in the Fund. The bar chart shows the performance of the Fund’s Class A Shares over the past five calendar years. The table shows the average annual total returns over the past one year, five years and the life of the Fund. The table compares that performance to the Morgan Stanley Capital International (MSCI) Russia Index (net of foreign withholding taxes) and the Lipper Emerging Markets Funds Index, an index based on the total return of certain funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111. The performance figures in the bar chart do not reflect any deduction for the front-end sales charge, which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 62% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests primarily in equity securities from developed countries included in the Morgan Stanley Capital International (MSCI) Europe, Australasia and Far East (EAFE) Value Index (net of foreign withholding taxes), which is the Fund’s benchmark. The Fund typically does not invest in U.S. companies.

Equity securities in which the Fund invests are common stocks, preferred stocks, convertible securities, depositary receipts, rights and warrants to buy common stocks and privately placed securities.

The Fund’s sector weightings generally approximate those of the MSCI EAFE Value Index, although the Fund does not seek to mirror the index in its choice of individual securities. In choosing stocks, the Fund emphasizes those that are ranked as undervalued according to the proprietary research of the adviser while underweighting or avoiding those that appear overvalued.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser employs a process that combines fundamental research for identifying portfolio securities and currency management decisions.

Various models are used to quantify the adviser’s fundamental stock research, producing a ranking of companies in each industry group according to their relative value. The Fund’s management team then buys and sells stocks, using the research and valuation rankings as well as its assessment of other factors, including:

• value characteristics such as low price-to-book and price-to-earnings ratios;

• catalysts that could trigger a change in a stock’s price;

• potential reward compared to potential risk; and

• temporary mispricings caused by market overreactions.

The Fund has access to the adviser’s currency specialists in determining the extent and nature of the Fund’s exposure to various foreign currencies.

The Fund may invest a substantial part of its assets in just one region or country.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Value Investing Risk. A value stock may decrease in price or may not increase in price as anticipated by the adviser if other investors fail to recognize the company’s value or the factors that the adviser believes will cause the stock price to increase do not occur.

Geographic Focus Risk. The Fund may focus its investments in a region or small group of countries. As a result, the Fund’s performance may be subject to greater volatility than a more geographically diversified fund.

Depositary Receipt Risk. The Fund’s investments may take the form of depositary receipts, including unsponsored depositary receipts. Unsponsored depositary receipts may not provide as much information about the underlying issuer and may not carry the same voting privileges as sponsored depositary receipts. Unsponsored depositary receipts are issued by one or more depositaries in response to market demand, but without a formal agreement with the company that issues the underlying securities.

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

To the extent that the Fund hedges its currency exposure, it may reduce the effects of currency fluctuations. The Fund may also hedge from one foreign currency to another. However, the Fund does not typically use this hedging strategy for its emerging markets currency exposure.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

The table compares that performance to the Morgan Stanley Capital International (MSCI), Europe, Australasia and Far East (EAFE) Value Index (net of foreign withholding taxes) and the Lipper International Large-Cap Value Funds Average, an average based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper average includes the expenses of the mutual funds included in the average. The performance of Class C Shares is based on the performance of Class B Shares prior to the inception of Class C Shares.

Portfolio Turnover

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 45% of the average value of its portfolio.

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses shown in the fee table. Your actual costs may be higher or lower.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund’s assets are invested primarily in equity securities of companies from developed countries other than the United States. The Fund’s assets may also be invested to a limited extent in emerging markets issuers. Developed countries include Australia, Canada, Japan, New Zealand, Hong Kong, Singapore, the United Kingdom, and most of the countries of Western Europe; emerging markets include most other countries in the world.

The equity securities in which the Fund may invest include, but are not limited to, common stock, preferred stock, convertible securities, trust or partnership interests, depositary receipts, privately placed securities and warrants and rights.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest.

The Fund will invest substantially in securities denominated in foreign currencies and may seek to manage currency risk where appropriate through managing currency exposure.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and securities selection.

The adviser selects securities for the Fund’s portfolio using its own investment process to determine which companies it believes are most likely to provide high total return to shareholders. The adviser chooses the most attractive securities in each sector and builds the portfolio bottom up. Securities in each industry are ranked with the help of fundamental valuations, then selected for investment. The adviser may adjust currency exposure to manage risks and enhance returns.

Through its extensive global equity research and analytical systems, the adviser seeks to generate an information advantage. Using fundamental analysis, the adviser develops proprietary research, primarily on companies but also on countries and currencies. In these processes, the analysts focus on a relatively long period rather than on near-term expectations alone.

Fundamental stock research is used to produce a ranking of companies in each industry group according to their relative value. The Fund’s adviser then buys and sells securities, using the research and valuation rankings as well as its assessment of other factors, including:

• catalysts that could trigger a change in a security’s price;

• potential reward compared to potential risk; and

• temporary mispricings caused by market overreactions.

The Fund may invest a substantial part of its assets in just one region or country.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R6 Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Morgan Stanley Capital International (MSCI), Europe, Australasia and Far East (EAFE) Index (net of foreign withholding taxes) and the Lipper International Large-Cap Core Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance for Class R6 Shares is based on the performance of Institutional Class Shares prior to the inception of the Class R6 Shares. The returns of the Class R6 Shares would have been different than those shown because Institutional Class Shares have different expenses than Class R6 Shares. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

Portfolio Turnover [Text Block]

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 49% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund will invest at least 80% of the value of its Assets in securities of Latin American issuers and other investments that are tied economically to Latin America. “Assets” means net assets, plus the amount of borrowings for investment purposes. Latin America includes, but is not limited to, Argentina, Brazil, Chile, Colombia, Ecuador, Guatemala, Mexico, Peru, Panama and Venezuela. The Fund will invest primarily in foreign companies of various sizes, including foreign subsidiaries of U.S. companies.

The Fund’s adviser considers a number of factors to determine whether an investment is tied economically to Latin America including: the source of government guarantees (if any); the primary trading market; the issuer’s domicile, sources of revenue, and location of assets; whether the investment is included in an index representative of a particular country in Latin America or the Latin American region; and whether the investment is exposed to the economic fortunes and risks of a particular country in Latin America or the Latin American region.

The Fund may overweight or underweight countries relative to its benchmark, the Morgan Stanley Capital International (MSCI) Emerging Markets (EM) Latin America Index (net of foreign withholding taxes).

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest. The Fund may from time to time hedge a portion of its foreign currency exposure into the U.S. dollar.

Investment Process: The adviser focuses on active and fundamental research, relying less on published data and more on subjective analysis conducted primarily through company visits by locally-based country specialists.

In managing the Fund, the adviser seeks to add value primarily through stock selection decisions. Thus, decisions about country weightings are secondary to those about the individual stocks, which make up the portfolio. The portfolio manager is primarily responsible for implementing the recommendations of our country specialists, who make their recommendations based on the stock ranking system.

The primary emphasis in selecting securities for the Fund is on bottom-up stock research conducted by country specialists, while macro research is used as a framework for the analysis.

The Fund will sell securities if the adviser believes the issuer of such securities no longer meets certain growth criteria, if certain political and economic events occur, or if it believes that more attractive opportunities are available.

The Fund is non-diversified.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Latin American Market Risk. The economies of countries in Latin America are all considered emerging market economies. High interest, inflation (in some cases substantial and prolonged), and unemployment rates generally characterize each economy. Because commodities such as agricultural products, minerals, and metals represent a significant percentage of exports of many Latin American countries, the economies of those countries are particularly sensitive to fluctuations in commodity prices. Investments in the region may also be subject to currency risks, such as restrictions on the flow of money in and out of the country, extreme volatility relative to the U.S. dollar, and devaluation, all of which could decrease the value of the Fund.

Governments of many Latin American countries exercise substantial influence over many aspects of the private sector, and any such exercise could have a significant effect on companies in which the Fund invests. Other Latin American market risks include foreign exchange controls, difficulties in pricing securities, defaults on sovereign debt, difficulties in enforcing favorable legal judgments in local courts and political and social instability.

Because the Fund concentrates in a single region of the world, the Fund’s performance may be more volatile than that of a fund that invests globally. If Latin American securities fall out of favor, it may cause the Fund to underperform funds that do not concentrate in a single region of the world.

Smaller Cap Company Risk. Investments in securities of smaller companies may be riskier and more volatile and vulnerable to economic, market and industry changes than securities of larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivatives Risk. Derivatives may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

Non-Diversified Fund Risk. Since the Fund is nondiversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased concentration in fewer issuers may result in the Fund’s shares being more sensitive to economic results of those issuing the securities.

High Portfolio Turnover Risk. The Fund will likely engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of the value of its Assets in equity securities of emerging markets. “Assets” means net assets, plus the amount of borrowings for investment purposes. Emerging markets include most countries in the world except Australia, Canada, Japan, New Zealand, Hong Kong, the United Kingdom, the United States, and most of the countries of Western Europe.

The Fund may overweight or underweight countries relative to its benchmark, the Morgan Stanley Capital International (MSCI) Emerging Markets (EM) Index (net of foreign withholding taxes).

The adviser attempts to emphasize securities that it believes are undervalued, while underweighting or avoiding securities that appear to the adviser to be overvalued.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest. The Fund typically maintains full currency exposure to those markets in which it invests. However, the Fund may from time to time hedge a portion of its foreign currency exposure into the U.S. dollar.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: The adviser seeks to add value primarily through stock selection decisions. Thus, decisions about country weightings are secondary to those about the individual stocks, which make up the portfolio. The portfolio managers are primarily responsible for implementing the recommendations of the country specialists, who make their recommendations based on the stock ranking system.

Country specialists use their local expertise to identify, research, and rank companies according to their expected performance. Stocks are assessed using a two-part analysis which considers both expected short-term price moves (stock ranks) and longer-term business growth characteristics and qualitative factors (strategic classifications). In order to encourage creativity, considerable autonomy is given to country specialists at the stock idea generation stage of the process.

The Fund has access to the adviser’s currency specialists in determining the extent and nature of the Fund’s exposure to various foreign currencies.

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the table through 2/28/14 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

IF YOU SELL YOUR SHARES, YOUR COST WOULD BE:

Expense Example A, B, C, Select Shares JPMorgan International Value Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	655	934	1,234	2,083
CLASS B SHARES	688	886	1,209	2,059
CLASS C SHARES	288	586	1,009	2,189
SELECT CLASS SHARES	112	354	615	1,361

IF YOU DO NOT SELL YOUR SHARES, YOUR COST
WOULD BE:

Expense Example, No Redemption A, B, C, Select Shares JPMorgan International Value Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	655	934	1,234	2,083
CLASS B SHARES	188	586	1,009	2,059
CLASS C SHARES	188	586	1,009	2,189
SELECT CLASS SHARES	112	354	615	1,361

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 62% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund invests primarily in equity securities from developed countries included in the Morgan Stanley Capital International (MSCI) Europe, Australasia and Far East (EAFE) Value Index (net of foreign withholding taxes), which is the Fund’s benchmark. The Fund typically does not invest in U.S. companies.

Equity securities in which the Fund invests are common stocks, preferred stocks, convertible securities, depositary receipts, rights and warrants to buy common stocks and privately placed securities.

The Fund’s sector weightings generally approximate those of the MSCI EAFE Value Index, although the Fund does not seek to mirror the index in its choice of individual securities. In choosing stocks, the Fund emphasizes those that are ranked as undervalued according to the proprietary research of the adviser while underweighting or avoiding those that appear overvalued.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser employs a process that combines fundamental research for identifying portfolio securities and currency management decisions.

Various models are used to quantify the adviser’s fundamental stock research, producing a ranking of companies in each industry group according to their relative value. The Fund’s management team then buys and sells stocks, using the research and valuation rankings as well as its assessment of other factors, including:

• value characteristics such as low price-to-book and price-to-earnings ratios;

• catalysts that could trigger a change in a stock’s price;

• potential reward compared to potential risk; and

• temporary mispricings caused by market overreactions.

The Fund has access to the adviser’s currency specialists in determining the extent and nature of the Fund’s exposure to various foreign currencies.

The Fund may invest a substantial part of its assets in just one region or country.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Value Investing Risk. A value stock may decrease in price or may not increase in price as anticipated by the adviser if other investors fail to recognize the company’s value or the factors that the adviser believes will cause the stock price to increase do not occur.

Geographic Focus Risk. The Fund may focus its investments in a region or small group of countries. As a result, the Fund’s performance may be subject to greater volatility than a more geographically diversified fund.

Depositary Receipt Risk. The Fund’s investments may take the form of depositary receipts, including unsponsored depositary receipts. Unsponsored depositary receipts may not provide as much information about the underlying issuer and may not carry the same voting privileges as sponsored depositary receipts. Unsponsored depositary receipts are issued by one or more depositaries in response to market demand, but without a formal agreement with the company that issues the underlying securities.

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

To the extent that the Fund hedges its currency exposure, it may reduce the effects of currency fluctuations. The Fund may also hedge from one foreign currency to another. However, the Fund does not typically use this hedging strategy for its emerging markets currency exposure.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows the performance of the Fund’s Select Class Shares over the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Morgan Stanley Capital International (MSCI), Europe, Australasia and Far East (EAFE) Value Index (net of foreign withholding taxes) and the Lipper International Large-Cap Value Funds Average, an average based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper average includes the expenses of the mutual funds included in the average. The performance of Class C Shares is based on the performance of Class B Shares prior to the inception of Class C Shares. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

SELECT CLASS SHARES	108	337	585	1,294

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 45% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund’s assets are invested primarily in equity securities of companies from developed countries other than the United States. The Fund’s assets may also be invested to a limited extent in emerging markets issuers. Developed countries include Australia, Canada, Japan, New Zealand, Hong Kong, Singapore, the United Kingdom, and most of the countries of Western Europe; emerging markets include most other countries in the world.

The equity securities in which the Fund may invest include, but are not limited to, common stock, preferred stock, convertible securities, trust or partnership interests, depositary receipts, privately placed securities and warrants and rights.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest.

The Fund will invest substantially in securities denominated in foreign currencies and may seek to manage currency risk where appropriate through managing currency exposure.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and securities selection.

The adviser selects securities for the Fund’s portfolio using its own investment process to determine which companies it believes are most likely to provide high total return to shareholders. The adviser chooses the most attractive securities in each sector and builds the portfolio bottom up. Securities in each industry are ranked with the help of fundamental valuations, then selected for investment. The adviser may adjust currency exposure to manage risks and enhance returns.

Through its extensive global equity research and analytical systems, the adviser seeks to generate an information advantage. Using fundamental analysis, the adviser develops proprietary research, primarily on companies but also on countries and currencies. In these processes, the analysts focus on a relatively long period rather than on near-term expectations alone.

Fundamental stock research is used to produce a ranking of companies in each industry group according to their relative value. The Fund’s adviser then buys and sells securities, using the research and valuation rankings as well as its assessment of other factors, including:

• catalysts that could trigger a change in a security’s price;
• potential reward compared to potential risk; and
• temporary mispricings caused by market overreactions.

The Fund may invest a substantial part of its assets in just one region or country.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Morgan Stanley Capital International (MSCI), Europe, Australasia and Far East (EAFE) Index (net of foreign withholding taxes) and the Lipper International Large-Cap Core Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance of Class C Shares is based on the performance of Class B Shares prior to the inception of Class C Shares. The actual returns of Class C Shares would have been similar to those shown because they have similar expenses to Class B Shares. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 297% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund invests primarily in equity securities issued by companies with principal business activities in Western Europe. Under normal market conditions, the Fund invests at least 80% of the value of its Assets in equity securities of European issuers. “Assets” means net assets, plus the amount of borrowings for investment purposes.

The Fund may utilize exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser uses a bottom-up stock selection process that focuses on the value, quality and momentum characteristics to decide which stocks to buy and sell.

The Fund may invest in Austria, Belgium, Denmark, Germany, Finland, France, Greece, Ireland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, and the United Kingdom, as well as other Western European countries which the adviser believes are appropriate. In addition, the Fund may invest up to 8% of its Assets in equity securities of emerging market European issuers. These countries may include Poland, the Czech Republic, Hungary and other countries with similar economic profiles which the adviser believes are appropriate.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest. The adviser may adjust the Fund’s exposure to each currency based on its view of the markets and issuers. It may increase or decrease the emphasis on a type of security, sector, country or currency, based on its analysis of a variety of economic factors, including fundamental economic strength, earnings growth, quality of management, sector growth, credit quality and interest rate trends. The Fund may purchase securities where the issuer is located in one country but the security is denominated in the currency of another.

While the Fund’s assets will usually be invested in a number of different Western European countries, the Fund may at times invest most or all of the assets in a limited number of these countries. The Fund will, however, try to choose a wide range of industries and companies of varying sizes.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

European Market Risk. The Fund’s performance will be affected by political, social and economic conditions in Europe, such as growth of the economic output (the gross national product), the rate of inflation, the rate at which capital is reinvested into European economies, the resource self-sufficiency of European countries and interest and monetary exchange rates between European countries. European financial markets may experience volatility due to concerns about high government debt levels, credit rating downgrades, the future of the euro as a common currency, possible restructuring of government debt and other government measures responding to those concerns. In addition, if one or more countries were to abandon the use of the euro as a currency, the value of investments tied to those countries or the euro could decline significantly and unpredictably.

Derivatives Risk. Derivatives, including futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

High Portfolio Turnover Risk. The Fund will likely engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Institutional Class Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Morgan Stanley Capital International (MSCI) Europe Index (net of foreign withholding taxes) and the Lipper European Region Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 85% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund will invest at least 80% of the value of its Assets in equity securities of companies in the China region or instruments that have similar economic characteristics. “Assets” means net assets, plus the amount of borrowings for investment purposes. A company in the China region is one: that is organized under the laws of, or has a principal office in the People’s Republic of China, including Hong Kong and Macau (China), or Taiwan; the principal securities market for which is China or Taiwan; that derives at least 50% of its total revenues or profits from goods that are produced or sold, investments made, or services performed in China or Taiwan; or at least 50% of the assets of which are located in China or Taiwan.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest. The Fund may from time to time hedge a portion of its foreign currency exposure into the U.S. dollar.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: The Fund is managed by the sub-adviser using an active investment management style which focuses on both an analysis of macro factors and bottom-up stock selection. Given the sub-adviser’s belief that the direction of the economy and stock markets in the China region, particularly China and Hong Kong, are closely linked to macro factors such as government policies, global economic data, commodities prices and supply/demand dynamics, the sub-adviser’s investment approach involves in-depth discussions and thorough analysis on these macro factors. The output of these analyses and discussions will serve as the building blocks for its sector and stock selection in individual countries.

In lieu of the limited public information available in the China region, the sub-adviser conducts internal research and analysis on both macro economic factors and stock fundamentals, and relies less on third-party data. The sub-adviser’s decisions are made primarily through subjective analysis and insights the sub-adviser gathered through company meetings and communications conducted by the country specialists based in Shanghai, Hong Kong and Taipei. In addition, the sub-adviser has access to the financial skills and research capabilities of certain of the region’s established investment banks.

Stock selection is also an important part of the subadviser’s investment process. In general, the sub-adviser covers approximately 75–80% of the investable universe of China region companies and updates stock views on a weekly basis. The stock selection process is largely country specific, whereby individual country specialists have the responsibility to design and refine their stock selection process to cope with the dynamic local factors and market conditions. Apart from analyzing the impact of macro factors such as government policies and global economic data on individual stocks, there are also several common factors that the country specialists always focus on, such as:

• competitive dynamics
• industry structures
• cyclicality and evolution
• growth
• corporate governance
• liquidity

In addition, country specialists particularly emphasize the following factors in stock selection: sustainability of competitive advantage; high and/or expanding returns on equity; and earnings per share growth.

Country specialists are encouraged to visit a wide range of companies across a variety of sectors, and it is from these company visits that the sub-adviser can make qualitative assessments of the relative growth prospects of the companies concerned and their strategies to create shareholder value. The sub-adviser analyzes industries in which companies operate, the competitive landscape as well as the management strategy to enhance competitive advantage and returns. As part of the investment process, the country specialists not only meet with some of the companies which fall within their core stock coverage, but they also meet with some of their competitors, distributors, suppliers and other stakeholders in order to obtain a complete analysis of the industry/company and other investment opportunities.

The Fund will sell securities if the sub-adviser believes the issuer of such securities no longer meets certain growth criteria, if certain political and economic events occur, or if it believes that more attractive opportunities are available.

The Fund is non-diversified.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

China Region Risk. In additional to the risks listed under “Foreign Securities and Emerging Markets Risks” investments in China, Hong Kong and Taiwan are subject to legal, regulatory, monetary and economic risks. Investments involve political and legal uncertainties, currency fluctuations and currency controls, the risk of confiscatory taxation, and nationalization or expropriation of assets. The Chinese securities markets are emerging markets characterized by greater price volatility. China is dominated by the one-party rule of the Communist Party, and the Chinese government exercises significant control over China’s economic growth. Though Taiwan is not dominated by one-party rule and employs a free market economy, Taiwan’s political and economic relationship with China, particularly the continuing disagreement as to Taiwan’s sovereignty, could adversely impact investments in Taiwan.

At times, there may be a high correlation among the Chinese and Taiwanese markets. Accordingly, because the Fund may invest a significant portion of its assets in these markets, it is subject to greater risks of adverse events that occur in those markets and may experience greater volatility than a fund that is more broadly diversified geographically.

Smaller Cap Company Risk. Investments in securities of smaller companies may be riskier and more volatile and vulnerable to economic, market and industry changes than securities of larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

Non-Diversified Fund Risk. Since the Fund is nondiversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased concentration in fewer issuers may result in the Fund’s shares being more sensitive to economic results of those issuing the securities.

High Portfolio Turnover Risk. The Fund will likely engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

R6 Shares | JPMorgan International Opportunities Fund

JPMorgan International Opportunities Fund

Class/Ticker: R6/JIOMX

What is the goal of the Fund?

The Fund seeks to provide high total return from a portfolio of equity securities of foreign companies in developed and, to a lesser extent, emerging markets.

Fees and Expenses of the Fund

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.

ANNUAL FUND OPERATING EXPENSES
(Expenses that you pay each year as a percentage of the value
of your investment)

Annual Fund Operating Expenses	R6 Shares JPMorgan International Opportunities Fund Class R6
Management Fees	0.60%
Distribution (Rule 12b-1) Fees	none
Other Expenses	0.19%
Shareholder Service Fees	none
Remainder of Other Expenses	0.19%

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses shown in the fee table. Your actual costs may be higher or lower.

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR

COST WOULD BE:

Expense Example, No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
R6 Shares JPMorgan International Opportunities Fund CLASS R6 SHARES	82	255	444	990

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 45% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund’s assets are invested primarily in equity securities of companies from developed countries other than the United States. The Fund’s assets may also be invested to a limited extent in emerging markets issuers. Developed countries include Australia, Canada, Japan, New Zealand, Hong Kong, Singapore, the United Kingdom, and most of the countries of Western Europe; emerging markets include most other countries in the world.

The equity securities in which the Fund may invest include, but are not limited to, common stock, preferred stock, convertible securities, trust or partnership interests, depositary receipts, privately placed securities and warrants and rights.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest.

The Fund will invest substantially in securities denominated in foreign currencies and may seek to manage currency risk where appropriate through managing currency exposure.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and securities selection.

The adviser selects securities for the Fund’s portfolio using its own investment process to determine which companies it believes are most likely to provide high total return to shareholders. The adviser chooses the most attractive securities in each sector and builds the portfolio bottom up. Securities in each industry are ranked with the help of fundamental valuations, then selected for investment. The adviser may adjust currency exposure to manage risks and enhance returns.

Through its extensive global equity research and analytical systems, the adviser seeks to generate an information advantage. Using fundamental analysis, the adviser develops proprietary research, primarily on companies but also on countries and currencies. In these processes, the analysts focus on a relatively long period rather than on near-term expectations alone.

Fundamental stock research is used to produce a ranking of companies in each industry group according to their relative value. The Fund’s adviser then buys and sells securities, using the research and valuation rankings as well as its assessment of other factors, including:

• catalysts that could trigger a change in a security’s price;

• potential reward compared to potential risk; and

• temporary mispricings caused by market overreactions.

The Fund may invest a substantial part of its assets in just one region or country.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this Prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R6 Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Morgan Stanley Capital International (MSCI), Europe, Australasia and Far East (EAFE) Index (net of foreign withholding taxes) and the Lipper International Large-Cap Core Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance for Class R6 Shares is based on the performance of Institutional Class Shares prior to the inception of the Class R6 Shares. The returns of the Class R6 Shares would have been different than those shown because Institutional Class Shares have different expenses than Class R6 Shares. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

Actual after-tax returns depend on the investor’s tax situation and may differ from those shown, and the after-tax returns shown are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

The Fund’s assets are invested primarily in equity securities of companies from developed countries other than the U.S. The Fund’s assets also may be invested, to a limited extent, in equity securities of companies from emerging markets. Developed countries include Australia, Canada, Japan, New Zealand, Hong Kong, the United Kingdom and most of the countries of Western Europe; emerging markets include most of the other countries in the world.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest.

The Fund may utilize currency forwards to manage currency exposure of its foreign investments relative to its benchmark. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser adheres to a disciplined process for stock selection and portfolio construction. A proprietary multifactor model is used to quantitatively rank securities in the Fund’s investment universe on the basis of value and growth factors. Value is measured by valuation multiples, while momentum is captured by factors such as relative price strength and earnings revisions. Securities held in the Fund that have become over-valued and/or whose growth signals have deteriorated materially may be sold. Securities that are sold are generally replaced with the most attractive securities, on the basis of the adviser’s disciplined investment process.

The portfolio construction process controls for sector and industry weights, number of stocks held, and position size. Risk or factor exposures are actively managed through portfolio construction.

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets.

These risks are magnified in “emerging markets.”

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives.

Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

High Portfolio Turnover Risk. The Fund will likely engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the table through 2/28/14 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 85% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal market conditions, the Fund will invest at least 80% of the value of its Assets in equity securities of companies in the China region or instruments that have similar economic characteristics. “Assets” means net assets, plus the amount of borrowings for investment purposes. A company in the China region is one: that is organized under the laws of, or has a principal office in the People’s Republic of China, including Hong Kong and Macau (China), or Taiwan; the principal securities market for which is China or Taiwan; that derives at least 50% of its total revenues or profits from goods that are produced or sold, investments made, or services performed in China or Taiwan; or at least 50% of the assets of which are located in China or Taiwan.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest. The Fund may from time to time hedge a portion of its foreign currency exposure into the U.S. dollar.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: The Fund is managed by the sub-adviser using an active investment management style which focuses on both an analysis of macro factors and bottom-up stock selection. Given the sub-adviser’s belief that the direction of the economy and stock markets in the China region, particularly China and Hong Kong, are closely linked to macro factors such as government policies, global economic data, commodities prices and supply/demand dynamics, the sub-adviser’s investment approach involves in-depth discussions and thorough analysis on these macro factors. The output of these analyses and discussions will serve as the building blocks for its sector and stock selection in individual countries.

In lieu of the limited public information available in the China region, the sub-adviser conducts internal research and analysis on both macro economic factors and stock fundamentals, and relies less on third-party data. The sub-adviser’s decisions are made primarily through subjective analysis and insights the sub-adviser gathered through company meetings and communications conducted by the country specialists based in Shanghai, Hong Kong and Taipei. In addition, the sub-adviser has access to the financial skills and research capabilities of certain of the region’s established investment banks.

Stock selection is also an important part of the subadviser’s investment process. In general, the sub-adviser covers approximately 75–80% of the investable universe of China region companies and updates stock views on a weekly basis. The stock selection process is largely country specific, whereby individual country specialists have the responsibility to design and refine their stock selection process to cope with the dynamic local factors and market conditions. Apart from analyzing the impact of macro factors such as government policies and global economic data on individual stocks, there are also several common factors that the country specialists always focus on, such as:

• competitive dynamics
• industry structures
• cyclicality and evolution
• growth
• corporate governance
• liquidity

In addition, country specialists particularly emphasize the following factors in stock selection: sustainability of competitive advantage; high and/or expanding returns on equity; and earnings per share growth.

Country specialists are encouraged to visit a wide range of companies across a variety of sectors, and it is from these company visits that the sub-adviser can make qualitative assessments of the relative growth prospects of the companies concerned and their strategies to create shareholder value. The sub-adviser analyzes industries in which companies operate, the competitive landscape as well as the management strategy to enhance competitive advantage and returns. As part of the investment process, the country specialists not only meet with some of the companies which fall within their core stock coverage, but they also meet with some of their competitors, distributors, suppliers and other stakeholders in order to obtain a complete analysis of the industry/company and other investment opportunities.

The Fund will sell securities if the sub-adviser believes the issuer of such securities no longer meets certain growth criteria, if certain political and economic events occur, or if it believes that more attractive opportunities are available.

The Fund is non-diversified.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

China Region Risk. In additional to the risks listed under “Foreign Securities and Emerging Markets Risks” investments in China, Hong Kong and Taiwan are subject to legal, regulatory, monetary and economic risks. Investments involve political and legal uncertainties, currency fluctuations and currency controls, the risk of confiscatory taxation, and nationalization or expropriation of assets. The Chinese securities markets are emerging markets characterized by greater price volatility. China is dominated by the one-party rule of the Communist Party, and the Chinese government exercises significant control over China’s economic growth. Though Taiwan is not dominated by one-party rule and employs a free market economy, Taiwan’s political and economic relationship with China, particularly the continuing disagreement as to Taiwan’s sovereignty, could adversely impact investments in Taiwan.

At times, there may be a high correlation among the Chinese and Taiwanese markets. Accordingly, because the Fund may invest a significant portion of its assets in these markets, it is subject to greater risks of adverse events that occur in those markets and may experience greater volatility than a fund that is more broadly diversified geographically.

Smaller Cap Company Risk. Investments in securities of smaller companies may be riskier and more volatile and vulnerable to economic, market and industry changes than securities of larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

Non-Diversified Fund Risk. Since the Fund is nondiversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased concentration in fewer issuers may result in the Fund’s shares being more sensitive to economic results of those issuing the securities.

High Portfolio Turnover Risk. The Fund will likely engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past five calendar years. The table shows the average annual total returns over the past one year, five years and the life of the Fund. The table compares that performance to the Morgan Stanley Capital International (MSCI) Golden Dragon Index (net of foreign withholding taxes) and the Lipper China Region Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111. The performance figures in the bar chart do not reflect any deduction for the front-end sales charge, which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of the value of its Assets in equity securities of emerging markets. “Assets” means net assets, plus the amount of borrowings for investment purposes. Emerging markets include most countries in the world except Australia, Canada, Japan, New Zealand, Hong Kong, the United Kingdom, the United States, and most of the countries of Western Europe.

The Fund may overweight or underweight countries relative to its benchmark, the Morgan Stanley Capital International (MSCI) Emerging Markets (EM) Index (net of foreign withholding taxes). The adviser attempts to emphasize securities that it believes are undervalued, while underweighting or avoiding securities that appear to the adviser to be overvalued.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest. The Fund typically maintains full currency exposure to those markets in which it invests. However, the Fund may from time to time hedge a portion of its foreign currency exposure into the U.S. dollar.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund the adviser seeks to add value primarily through stock selection decisions. Thus, decisions about country weightings are secondary to those about the individual stocks, which make up the portfolio. The portfolio managers are primarily responsible for implementing the recommendations of the country specialists, who make their recommendations based on the stock ranking system.

Country specialists use their local expertise to identify, research, and rank companies according to their expected performance. Stocks are assessed using a two-part analysis which considers both expected short-term price moves (stock ranks) and longer-term business growth characteristics and qualitative factors (strategic classifications). In order to encourage creativity, considerable autonomy is given to country specialists at the stock idea generation stage of the process.

The Fund has access to the adviser’s currency specialists in determining the extent and nature of the Fund’s exposure to various foreign currencies.

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets.

Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets.

Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars.

Portfolio Turnover [Text Block]

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 5% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal conditions, the Fund will invest at least 80% of the value of its Assets in equity investments. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund will primarily invest in foreign companies of various market capitalizations, including foreign subsidiaries of U.S. companies.

The equity securities in which the Fund may invest include, but are not limited to, common stock, preferred stock, convertible securities, trust or partnership interests, depositary receipts and warrants and rights.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest.

The Fund may utilize currency forwards to manage currency exposure of its foreign investments relative to its benchmark. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser will seek to help manage risk in the Fund’s portfolio by investing in issuers in at least three different countries other than the United States. However, the Fund may invest a substantial part of its assets in just one region or country.

The Fund intends to invest in companies (or governments) in the following countries or regions: the Far East (including Japan, Hong Kong, Singapore and Malaysia), Western Europe (including the United Kingdom, Germany, the Netherlands, France, Switzerland, Italy, Scandinavia and Spain), Australia, Canada and other countries or areas that the adviser may select from time to time. A substantial part of the Fund’s assets may be invested in U.S. companies based in countries that are represented in the Morgan Stanley Capital International (MSCI), Europe, Australasia and Far East (EAFE) Index. However, the Fund may also invest in companies or governments in emerging markets.

The adviser may adjust the Fund’s exposure to each currency based on its view of the markets and issuers. The adviser will decide how much to invest in the securities of a particular country or currency by evaluating the yield and potential growth of an investment, as well as the relationship between the currency and the U.S. dollar. The adviser may increase or decrease the emphasis on a type of security, sector, country or currency, based on its analysis of a variety of economic factors, including fundamental economic strength, earnings growth, quality of management, sector growth, credit quality and interest rate trends. The Fund may purchase securities where the issuer is located in one country but the security is denominated in the currency of another.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Geographic Focus Risk. The Fund may focus its investments in a region or small group of countries. As a result, the Fund’s performance may be subject to greater volatility than a more geographically diversified fund.

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R5 Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Morgan Stanley Capital International (MSCI), Europe, Australasia and Far East (EAFE) Index (net of foreign withholding taxes) and the Lipper International Large-Cap Core Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance of Class R5 Shares prior to their inception is based on the performance of Select Class Shares. The actual returns of the Class R5 Shares would have been different than those shown because Class R5 Shares have different expenses than Select Class Shares. The performance of Class R2 Shares prior to their inception is based on the performance of Class A Shares. The actual returns of Class R2 Shares would have been lower than those shown because Class R2 Shares have higher expenses than Class A Shares. The performance of Class R6 Shares prior to their inception is based on the performance of Class R5 Shares and Select Class Shares prior to the inception of Class R5 Shares. The actual returns of Class R6 Shares would have been different than those shown because Class R6 Shares have different expenses than Select Class Shares and Class R5 Shares. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of the value of its Assets in equity securities of emerging markets companies and other investments that are tied economically to emerging markets. “Assets” means net assets, plus the amount of borrowings for investment purposes. Emerging markets include most countries in the world except Australia, Canada, Japan, New Zealand, Hong Kong, the United Kingdom, the United States, and most of the countries of Western Europe. An emerging market company is one: that is organized under the laws of, or has a principal place of business in an emerging market; where the principal securities market is in an emerging market; that derives at least 50% of its total revenues or profits from goods that are produced or sold, investments made, or services performed in an emerging market; or at least 50% of the assets of which are located in an emerging market.

The Fund is not required to allocate its investments in any set percentages in any particular countries. The Fund is not constrained by capitalization or style limits and will invest across sectors. The Fund will invest in securities across all market capitalizations, although the Fund may invest a significant portion of its assets in companies of any one particular market capitalization category.

The Fund may overweight or underweight countries relative to its benchmark, the Morgan Stanley Capital International (MSCI) Emerging Markets (EM) Index (net of foreign withholding taxes). The Fund emphasizes securities that are ranked as undervalued, while underweighting or avoiding securities that appear overvalued.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest. The Fund typically maintains full currency exposure to those markets in which it invests. However, the Fund may hedge a portion of its foreign currency exposure into the U.S. dollar.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may use exchange-traded futures for the efficient management of cash flows. The Fund may also use participation notes in the management of portfolio assets.

Investment Process: The adviser believes that emerging markets are generally inefficient as demonstrated by the high and variable volatility of many emerging markets and individual companies in these markets. Corporate disclosure and transparency can vary widely thereby exacerbating the inefficiency of these markets and offering opportunities to experienced, well-informed active investors.

In managing the Fund, the adviser adheres to a disciplined process for stock selection and portfolio construction. A proprietary multi-factor model is used to quantitatively rank securities in the Fund’s investment universe which the adviser uses to select securities. Securities held in the Fund that the adviser believes have become over-valued and/or whose factor signals have deteriorated materially may be sold and are generally replaced with more attractive securities, on the basis of the adviser’s disciplined investment process.

The portfolio construction process controls for country and sector weights, number of stocks held, and position size. Risk or factor exposures are actively managed through portfolio construction.

The Fund has access to the adviser’s currency specialists in determining the extent and nature of the Fund’s exposure to various foreign currencies.

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Smaller Cap Company Risk. Investments in securities of smaller companies may be riskier and more volatile and vulnerable to economic, market and industry changes than securities of larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivatives Risk. Derivatives, including forward currency contracts, futures and participation notes may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Preferred Stock Risk. Preferred stock generally has a preference as to dividends and liquidation over an issuer’s common stock but ranks junior to debt securities in an issuer’s capital structure. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

High Portfolio Turnover Risk. The Fund will likely engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 297% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests primarily in equity securities issued by companies with principal business activities in Western Europe. Under normal market conditions, the Fund invests at least 80% of the value of its Assets in equity securities of European issuers. “Assets” means net assets, plus the amount of borrowings for investment purposes.

The Fund may utilize exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser uses a bottom-up stock selection process that focuses on the value, quality and momentum characteristics to decide which stocks to buy and sell.

The Fund may invest in Austria, Belgium, Denmark, Germany, Finland, France, Greece, Ireland, Italy, Luxembourg, the Nether-lands, Norway, Portugal, Spain, Sweden, Switzerland, and the United Kingdom, as well as other Western European countries which the adviser believes are appropriate. In addition, the Fund may invest up to 8% of its Assets in equity securities of emerging market European issuers. These countries may include Poland, the Czech Republic, Hungary and other countries with similar economic profiles which the adviser believes are appropriate.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest. The adviser may adjust the Fund’s exposure to each currency based on its view of the markets and issuers. It may increase or decrease the emphasis on a type of security, sector, country or currency, based on its analysis of a variety of economic factors, including fundamental economic strength, earnings growth, quality of management, sector growth, credit quality and interest rate trends. The Fund may purchase securities where the issuer is located in one country but the security is denominated in the currency of another.

While the Fund’s assets will usually be invested in a number of different Western European countries, the Fund may at times invest most or all of the assets in a limited number of these countries. The Fund will, however, try to choose a wide range of industries and companies of varying sizes.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

European Market Risk. The Fund’s performance will be affected by political, social and economic conditions in Europe, such as growth of the economic output (the gross national product), the rate of inflation, the rate at which capital is reinvested into European economies, the resource self-sufficiency of European countries and interest and monetary exchange rates between European countries. European financial markets may experience volatility due to concerns about high government debt levels, credit rating downgrades, the future of the euro as a common currency, possible restructuring of government debt and other government measures responding to those concerns. In addition, if one or more countries were to abandon the use of the euro as a currency, the value of investments tied to those countries or the euro could decline significantly and unpredictably.

Derivatives Risk. Derivatives, including futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

High Portfolio Turnover Risk. The Fund will likely engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

R2 Shares | JPMorgan Intrepid International Fund

JPMorgan Intrepid International Fund

Class/Ticker: R2/JIIZX

What is the goal of the Fund?

The Fund seeks to maximize long-term capital growth by investing primarily in equity securities in developed markets outside the U.S.

Fees and Expenses of the Fund

The following table describes the fees and expenses that you may pay if you buy and hold shares of the Fund.

ANNUAL FUND OPERATING EXPENSES
(Expenses that you pay each year as a percentage of the
value of your investment)

Annual Fund Operating Expenses		R2 Shares JPMorgan Intrepid International Fund Class R2
Management Fees		0.85%
Distribution (Rule 12b-1) Fees		0.50%
Other Expenses		0.52%
Shareholder Service Fees		0.25%
Remainder of Other Expenses		0.27%
Acquired Fund Fees and Expenses		0.01%
Total Annual Fund Operating Expenses		1.88%
Fee Waivers and Expense Reimbursements	[1]	(0.12%)
Total Annual Fund Operating Expenses After Fee Waivers and Expense Reimbursements	[1]	1.76%

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the table through 2/28/14 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR
COST WOULD BE:

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
R2 Shares JPMorgan Intrepid International Fund CLASS R2 SHARES	179	579	1,005	2,191

WHETHER OR NOT YOU SELL YOUR SHARES, YOUR
COST WOULD BE:

Expense Example, No Redemption (USD $)	1 Year	3 Years	5 Years	10 Years
R2 Shares JPMorgan Intrepid International Fund CLASS R2 SHARES	179	579	1,005	2,191

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 46% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund’s assets are invested primarily in equity securities of companies from developed countries other than the U.S. The Fund’s assets also may be invested, to a limited extent, in equity securities of companies from emerging markets. Developed countries include Australia, Canada, Japan, New Zealand, Hong Kong, the United Kingdom and most of the countries of Western Europe; emerging markets include most of the other countries in the world.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest.

The Fund may utilize currency forwards to manage currency exposure of its foreign investments relative to its benchmark. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser adheres to a disciplined process for stock selection and portfolio construction. A proprietary multifactor model is used to quantitatively rank securities in the Fund’s investment universe on the basis of value and growth factors. Value is measured by valuation multiples, while momentum is captured by factors such as relative price strength and earnings revisions. Securities held in the Fund that have become over-valued and/or whose growth signals have deteriorated materially may be sold. Securities that are sold are generally replaced with the most attractive securities, on the basis of the adviser’s disciplined investment process.

The portfolio construction process controls for sector and industry weights, number of stocks held, and position size. Risk or factor exposures are actively managed through portfolio construction.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

High Portfolio Turnover Risk. The Fund will likely engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R2 Shares has varied from year to year over the past ten calendar years. This provides some indication of the risks of investing in the Fund. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Morgan Stanley Capital International (MSCI) Europe, Australasia and Far East (EAFE) Index (net of foreign withholding taxes) and the Lipper International Multi-Cap Core Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance of Class R2 Shares is based on the performance of Class A Shares prior to the inception of Class R2 Shares. The actual returns of Class R2 Shares would have been lower than shown because Class R2 Shares have higher expenses than Class A Shares. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on the investor’s tax situation and may differ from those shown, and the after-tax returns shown are not relevant to investors who hold their shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal circumstances, the Fund invests at least 80% of the value of its Assets in equity securities of emerging markets companies and other investments that are tied economically to emerging markets. “Assets” means net assets, plus the amount of borrowings for investment purposes. Emerging markets include most countries in the world except Australia, Canada, Japan, New Zealand, Hong Kong, the United Kingdom, the United States, and most of the countries of Western Europe. An emerging market company is one: that is organized under the laws of, or has a principal place of business in an emerging market; where the principal securities market is in an emerging market; that derives at least 50% of its total revenues or profits from goods that are produced or sold, investments made, or services performed in an emerging market; or at least 50% of the assets of which are located in an emerging market.

The Fund is not required to allocate its investments in any set percentages in any particular countries. The Fund is not constrained by capitalization or style limits and will invest across sectors. The Fund will invest in securities across all market capitalizations, although the Fund may invest a significant portion of its assets in companies of any one particular market capitalization category.

The Fund may overweight or underweight countries relative to its benchmark, the Morgan Stanley Capital International (MSCI) Emerging Markets (EM) Index (net of foreign withholding taxes). The Fund emphasizes securities that are ranked as undervalued, while underweighting or avoiding securities that appear overvalued.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest. The Fund typically maintains full currency exposure to those markets in which it invests. However, the Fund may hedge a portion of its foreign currency exposure into the U.S. dollar.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may use exchange-traded futures for the efficient management of cash flows. The Fund may also use participation notes in the management of portfolio assets.

Investment Process: The adviser believes that emerging markets are generally inefficient as demonstrated by the high and variable volatility of many emerging markets and individual companies in these markets. Corporate disclosure and transparency can vary widely thereby exacerbating the inefficiency of these markets and offering opportunities to experienced, well-informed active investors.

In managing the Fund, the adviser adheres to a disciplined process for stock selection and portfolio construction. A proprietary multi-factor model is used to quantitatively rank securities in the Fund’s investment universe which the adviser uses to select securities. Securities held in the Fund that the adviser believes have become over-valued and/or whose factor signals have deteriorated materially may be sold and are generally replaced with more attractive securities, on the basis of the adviser’s disciplined investment process.

The portfolio construction process controls for country and sector weights, number of stocks held, and position size. Risk or factor exposures are actively managed through portfolio construction.

The Fund has access to the adviser’s currency specialists in determining the extent and nature of the Fund’s exposure to various foreign currencies.

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser's expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company's financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund's portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund's securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment’” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Smaller Cap Company Risk. Investments in securities of smaller companies may be riskier and more volatile and vulnerable to economic, market and industry changes than securities of larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivatives Risk. Derivatives, including forward currency contracts, futures and participation notes may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Preferred Stock Risk. Preferred stock generally has a preference as to dividends and liquidation over an issuer’s common stock but ranks junior to debt securities in an issuer’s capital structure. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

High Portfolio Turnover Risk. The Fund will likely engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Portfolio Turnover [Text Block]

rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 45% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund’s assets are invested primarily in equity securities of companies from developed countries other than the United States. The Fund’s assets may also be invested to a limited extent in emerging markets issuers. Developed countries include Australia, Canada, Japan, New Zealand, Hong Kong, Singapore, the United Kingdom, and most of the countries of Western Europe; emerging markets include most other countries in the world.

The equity securities in which the Fund may invest include, but are not limited to, common stock, preferred stock, convertible securities, trust or partnership interests, depositary receipts, privately placed securities and warrants and rights.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest.

The Fund will invest substantially in securities denominated in foreign currencies and may seek to enhance returns and manage currency risk where appropriate through managing currency exposure.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and securities selection.

The adviser selects securities for the Fund’s portfolio using its own investment process to determine which companies it believes are most likely to provide high total return to shareholders. The adviser chooses the most attractive securities in each sector and builds the portfolio bottom up. Securities in each industry are ranked with the help of fundamental valuations, then selected for investment. The adviser may adjust currency exposure to manage risks and enhance returns.

Through its extensive global equity research and analytical systems, the adviser seeks to generate an information advantage. Using fundamental analysis, the adviser develops proprietary research, primarily on companies but also on countries and currencies.

In these processes, the analysts focus on a relatively long period rather than on near-term expectations alone.

Fundamental stock research is used to produce a ranking of companies in each industry group according to their relative value. The Fund’s adviser then buys and sells securities, using the research and valuation rankings as well as its assessment of other factors, including:

• catalysts that could trigger a change in a security’s price;

• potential reward compared to potential risk; and

• temporary mispricings caused by market overreactions.

The Fund may invest a substantial part of its assets in just one region or country.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 5% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal conditions, the Fund will invest at least 80% of the value of its Assets in equity investments. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund will primarily invest in foreign companies of various market capitalizations, including foreign subsidiaries of U.S. companies.

The equity securities in which the Fund may invest include, but are not limited to, common stock, preferred stock, convertible securities, trust or partnership interests, depositary receipts and warrants and rights.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest.

The Fund may utilize currency forwards to manage currency exposure of its foreign investments relative to its benchmark. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser will seek to help manage risk in the Fund’s portfolio by investing in issuers in at least three different countries other than the United States. However, the Fund may invest a substantial part of its assets in just one region or country.

The Fund intends to invest in companies (or governments) in the following countries or regions: the Far East (including Japan, Hong Kong, Singapore and Malaysia), Western Europe (including the United Kingdom, Germany, the Netherlands, France, Switzerland, Italy, Scandinavia and Spain), Australia, Canada and other countries or areas that the adviser may select from time to time. A substantial part of the Fund’s assets may be invested in U.S. companies based in countries that are represented in the Morgan Stanley Capital International (MSCI), Europe, Australasia and Far East (EAFE) Index. However, the Fund may also invest in companies or governments in emerging markets.

The adviser may adjust the Fund’s exposure to each currency based on its view of the markets and issuers. The adviser will decide how much to invest in the securities of a particular country or currency by evaluating the yield and potential growth of an investment, as well as the relationship between the currency and the U.S. dollar. The adviser may increase or decrease the emphasis on a type of security, sector, country or currency, based on its analysis of a variety of economic factors, including fundamental economic strength, earnings growth, quality of management, sector growth, credit quality and interest rate trends. The Fund may purchase securities where the issuer is located in one country but the security is denominated in the currency of another.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Geographic Focus Risk. The Fund may focus its investments in a region or small group of countries. As a result, the Fund’s performance may be subject to greater volatility than a more geographically diversified fund.

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R5 Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Morgan Stanley Capital International (MSCI), Europe, Australasia and Far East (EAFE) Index (net of foreign withholding taxes) and the Lipper International Large-Cap Core Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance of Class R5 Shares prior to their inception is based on the performance of Select Class Shares. The actual returns of the Class R5 Shares would have been different than those shown because Class R5 Shares have different expenses than Select Class Shares. The performance of Class R2 Shares prior to their inception is based on the performance of Class A Shares. The actual returns of Class R2 Shares would have been lower than those shown because Class R2 Shares have higher expenses than Class A Shares. The performance of Class R6 Shares prior to their inception is based on the performance of Class R5 Shares and Select Class Shares prior to the inception of Class R5 Shares. The actual returns of Class R6 Shares would have been different than those shown because Class R6 Shares have different expenses than Select Class Shares and Class R5 Shares. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

CLASS R6 SHARES	87	276	480	1,071

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 62% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund invests primarily in equity securities from developed countries included in the Morgan Stanley Capital International (MSCI) Europe, Australasia and Far East (EAFE) Value Index (net of foreign withholding taxes), which is the Fund’s benchmark. The Fund typically does not invest in U.S. companies.

Equity securities in which the Fund invests are common stocks, preferred stocks, convertible securities, depositary receipts, rights and warrants to buy common stocks and privately placed securities.

The Fund’s sector weightings generally approximate those of the MSCI EAFE Value Index, although the Fund does not seek to mirror the index in its choice of individual securities. In choosing stocks, the Fund emphasizes those that are ranked as undervalued according to the proprietary research of the adviser while underweighting or avoiding those that appear overvalued.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser employs a process that combines fundamental research for identifying portfolio securities and currency management decisions.

Various models are used to quantify the adviser’s fundamental stock research, producing a ranking of companies in each industry group according to their relative value. The Fund’s management team then buys and sells stocks, using the research and valuation rankings as well as its assessment of other factors, including:

• value characteristics such as low price-to-book and price-to-earnings ratios;

• catalysts that could trigger a change in a stock’s price;

• potential reward compared to potential risk; and

• temporary mispricings caused by market overreactions.

The Fund has access to the adviser’s currency specialists in determining the extent and nature of the Fund’s exposure to various foreign currencies.

The Fund may invest a substantial part of its assets in just one region or country.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Value Investing Risk. A value stock may decrease in price or may not increase in price as anticipated by the adviser if other investors fail to recognize the company’s value or the factors that the adviser believes will cause the stock price to increase do not occur.

Geographic Focus Risk. The Fund may focus its investments in a region or small group of countries. As a result, the Fund’s performance may be subject to greater volatility than a more geographically diversified fund.

Depositary Receipt Risk. The Fund’s investments may take the form of depositary receipts, including unsponsored depositary receipts. Unsponsored depositary receipts may not provide as much information about the underlying issuer and may not carry the same voting privileges as sponsored depositary receipts. Unsponsored depositary receipts are issued by one or more depositaries in response to market demand, but without a formal agreement with the company that issues the underlying securities.

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

To the extent that the Fund hedges its currency exposure, it may reduce the effects of currency fluctuations. The Fund may also hedge from one foreign currency to another. However, the Fund does not typically use this hedging strategy for its emerging markets currency exposure.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R2 Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Morgan Stanley Capital International (MSCI), Europe, Australasia and Far East (EAFE) Value Index (net of foreign withholding taxes) and the Lipper International Large-Cap Value Funds Average, an average based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper average includes the expenses of the mutual funds included in the average. The performance of Class R2 Shares is based on the performance of Class A Shares prior to the inception of Class R2 Shares. The actual returns of Class R2 Shares would have been lower than shown because Class R2 Shares have higher expenses than Class A Shares. The performance for Class R6 Shares is based on the performance of Institutional Class Shares prior to the inception of the Class R6 Shares. The actual returns of the Class R6 Shares would have been different than those shown because Institutional Class Shares have different expenses than Class R6 Shares. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 72% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund invests at least 80% of the value of its Assets in equity securities of emerging markets companies and other investments that are tied economically to emerging markets. “Assets” means net assets, plus the amount of borrowings for investment purposes. Emerging markets include most countries in the world except Australia, Canada, Japan, New Zealand, Hong Kong, the United Kingdom, the United States, and most of the countries of Western Europe. An emerging market company is one: that is organized under the laws of, or has a principal place of business in an emerging market; where the principal securities market is in an emerging market; that derives at least 50% of its total revenues or profits from goods that are produced or sold, investments made, or services performed in an emerging market; or at least 50% of the assets of which are located in an emerging market.

The Fund is not required to allocate its investments in any set percentages in any particular countries. The Fund is not constrained by capitalization or style limits and will invest across sectors. The Fund will invest in securities across all market capitalizations, although the Fund may invest a significant portion of its assets in companies of any one particular market capitalization category.

The Fund may overweight or underweight countries relative to its benchmark, the Morgan Stanley Capital International (MSCI) Emerging Markets (EM) Index (net of foreign withholding taxes). The Fund emphasizes securities that are ranked as undervalued, while underweighting or avoiding securities that appear overvalued.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest. The Fund typically maintains full currency exposure to those markets in which it invests. However, the Fund may hedge a portion of its foreign currency exposure into the U.S. dollar.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may use exchange-traded futures for the efficient management of cash flows. The Fund may also use participation notes in the management of portfolio assets.

Investment Process: The adviser believes that emerging markets are generally inefficient as demonstrated by the high and variable volatility of many emerging markets and individual companies in these markets. Corporate disclosure and transparency can vary widely thereby exacerbating the inefficiency of these markets and offering opportunities to experienced, well-informed active investors.

In managing the Fund, the adviser adheres to a disciplined process for stock selection and portfolio construction. A proprietary multi-factor model is used to quantitatively rank securities in the Fund’s investment universe which the adviser uses to select securities. Securities held in the Fund that the adviser believes have become over-valued and/or whose factor signals have deteriorated materially may be sold and are generally replaced with more attractive securities, on the basis of the adviser’s disciplined investment process.

The portfolio construction process controls for country and sector weights, number of stocks held, and position size. Risk or factor exposures are actively managed through portfolio construction.

The Fund has access to the adviser’s currency specialists in determining the extent and nature of the Fund’s exposure to various foreign currencies.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Smaller Cap Company Risk. Investments in securities of smaller companies may be riskier and more volatile and vulnerable to economic, market and industry changes than securities of larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivatives Risk. Derivatives, including forward currency contracts, futures and participation notes may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Preferred Stock Risk. Preferred stock generally has a preference as to dividends and liquidation over an issuer’s common stock but ranks junior to debt securities in an issuer’s capital structure. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

High Portfolio Turnover Risk. The Fund will likely engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class R5 Shares has varied from year to year for the past four calendar years. The table shows the average annual total returns over the past one year and the life of the Fund. The table compares that performance to the Morgan Stanley Capital International (MSCI) Emerging Markets (EM) Index (net of foreign withholding taxes), and the Lipper Emerging Markets Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future.

SELECT CLASS SHARES	160	496	855	1,867

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 20% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund invests at least 80% of the value of its Assets in equity securities of emerging markets. “Assets” means net assets, plus the amount of borrowings for investment purposes. Emerging markets include most countries in the world except Australia, Canada, Japan, New Zealand, Hong Kong, the United Kingdom, the United States, and most of the countries of Western Europe.

The Fund may overweight or underweight countries relative to its benchmark, the Morgan Stanley Capital International (MSCI) Emerging Markets (EM) Index (net of foreign withholding taxes).

The adviser attempts to emphasize securities that it believes are undervalued, while underweighting or avoiding securities that appear to the adviser to be overvalued.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest. The Fund typically maintains full currency exposure to those markets in which it invests. However, the Fund may from time to time hedge a portion of its foreign currency exposure into the U.S. dollar.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: The adviser seeks to add value primarily through stock selection decisions. Thus, decisions about country weightings are secondary to those about the individual stocks, which make up the portfolio. The portfolio managers are primarily responsible for implementing the recommendations of the country specialists, who make their recommendations based on the stock ranking system.

Country specialists use their local expertise to identify, research, and rank companies according to their expected performance. Stocks are assessed using a two-part analysis which considers both expected short-term price moves (stock ranks) and longer-term business growth characteristics and qualitative factors (strategic classifications). In order to encourage creativity, considerable autonomy is given to country specialists at the stock idea generation stage of the process.

The Fund has access to the adviser’s currency specialists in determining the extent and nature of the Fund’s exposure to various foreign currencies.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests primarily in equity securities from developed countries included in the Morgan Stanley Capital International (MSCI) Europe, Australasia and Far East (EAFE) Value Index (net of foreign withholding taxes), which is the Fund’s benchmark. The Fund typically does not invest in U.S. companies.

Equity securities in which the Fund invests are common stocks, preferred stocks, convertible securities, depositary receipts, rights and warrants to buy common stocks and privately placed securities.

The Fund’s sector weightings generally approximate those of the MSCI EAFE Value Index, although the Fund does not seek to mirror the index in its choice of individual securities. In choosing stocks, the Fund emphasizes those that are ranked as undervalued according to the proprietary research of the adviser while underweighting or avoiding those that appear overvalued.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser employs a process that combines fundamental research for identifying portfolio securities and currency management decisions.

Various models are used to quantify the adviser’s fundamental stock research, producing a ranking of companies in each industry group according to their relative value. The Fund’s management team then buys and sells stocks, using the research and valuation rankings as well as its assessment of other factors, including:

• value characteristics such as low price-to-book and price-to-earnings ratios;

• catalysts that could trigger a change in a stock’s price;

• potential reward compared to potential risk; and

• temporary mispricings caused by market overreactions.

The Fund has access to the adviser’s currency specialists in determining the extent and nature of the Fund’s exposure to various foreign currencies.

The Fund may invest a substantial part of its assets in just one region or country.

These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Value Investing Risk. A value stock may decrease in price or may not increase in price as anticipated by the adviser if other investors fail to recognize the company’s value or the factors that the adviser believes will cause the stock price to increase do not occur.

Geographic Focus Risk. The Fund may focus its investments in a region or small group of countries. As a result, the Fund’s performance may be subject to greater volatility than a more geographically diversified fund.

Depositary Receipt Risk. The Fund’s investments may take the form of depositary receipts, including unsponsored depositary receipts. Unsponsored depositary receipts may not provide as much information about the underlying issuer and may not carry the same voting privileges as sponsored depositary receipts. Unsponsored depositary receipts are issued by one or more depositaries in response to market demand, but without a formal agreement with the company that issues the underlying securities.

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

To the extent that the Fund hedges its currency exposure, it may reduce the effects of currency fluctuations. The Fund may also hedge from one foreign currency to another. However, the Fund does not typically use this hedging strategy for its emerging markets currency exposure.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the table through 2/28/14 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

IF YOU SELL YOUR SHARES, YOUR COST WOULD BE:

Expense Example A, C, Select Shares JPMorgan Intrepid International Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	671	1,001	1,354	2,347
CLASS C SHARES	304	655	1,133	2,453
SELECT CLASS SHARES	128	425	744	1,647

IF YOU DO NOT SELL YOUR SHARES, YOUR COST
WOULD BE:

Expense Example, No Redemption A, C, Select Shares JPMorgan Intrepid International Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	671	1,001	1,354	2,347
CLASS C SHARES	204	655	1,133	2,453
SELECT CLASS SHARES	128	425	744	1,647

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 46% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund’s assets are invested primarily in equity securities of companies from developed countries other than the U.S. The Fund’s assets also may be invested, to a limited extent, in equity securities of companies from emerging markets. Developed countries include Australia, Canada, Japan, New Zealand, Hong Kong, the United Kingdom and most of the countries of Western Europe; emerging markets include most of the other countries in the world.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest.

The Fund may utilize currency forwards to manage currency exposure of its foreign investments relative to its benchmark. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser adheres to a disciplined process for stock selection and portfolio construction. A proprietary multifactor model is used to quantitatively rank securities in the Fund’s investment universe on the basis of value and growth factors. Value is measured by valuation multiples, while momentum is captured by factors such as relative price strength and earnings revisions. Securities held in the Fund that have become over-valued and/or whose growth signals have deteriorated materially may be sold. Securities that are sold are generally replaced with the most attractive securities, on the basis of the adviser’s disciplined investment process.

The portfolio construction process controls for sector and industry weights, number of stocks held, and position size. Risk or factor exposures are actively managed through portfolio construction.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

High Portfolio Turnover Risk. The Fund will likely engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Morgan Stanley Capital International (MSCI) Europe, Australasia and Far East (EAFE) Index (net of foreign withholding taxes) and the Lipper International Multi-Cap Core Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance of Class C Shares is based on the performance of Class A Shares prior to the inception of Class C Shares. Actual returns of Class C Shares would have been lower than those shown because Class C Shares have higher expenses than Class A Shares. The performance of Select Class Shares is based on the performance of Institutional Class Shares prior to the inception of Select Class Shares. Actual returns of Select Class Shares would have been lower than those shown because Select Class Shares have higher expenses than Institutional Class Shares. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111. The performance figures in the bar chart do not reflect any deduction for the front-end sales charge, which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

SELECT CLASS SHARES	109	381	673	1,506

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 5% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal conditions, the Fund will invest at least 80% of the value of its Assets in equity investments. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund will primarily invest in foreign companies of various market capitalizations , including foreign subsidiaries of U.S. companies.

The equity securities in which the Fund may invest include, but are not limited to, common stock, preferred stock, convertible securities, trust or partnership interests, depositary receipts and warrants and rights.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest.

The Fund may utilize currency forwards to manage currency exposure of its foreign investments relative to its benchmark. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser will seek to help manage risk in the Fund’s portfolio by investing in issuers in at least three different countries other than the United States. However, the Fund may invest a substantial part of its assets in just one region or country.

The Fund intends to invest in companies (or governments) in the following countries or regions: the Far East (including Japan, Hong Kong, Singapore and Malaysia), Western Europe (including the United Kingdom, Germany, the Netherlands, France, Switzerland, Italy, Scandinavia and Spain), Australia, Canada and other countries or areas that the adviser may select from time to time. A substantial part of the Fund’s assets may be invested in U.S. companies based in countries that are represented in the Morgan Stanley Capital International (MSCI), Europe, Australasia and Far East (EAFE) Index. However, the Fund may also invest in companies or governments in emerging markets.

The adviser may adjust the Fund’s exposure to each currency based on its view of the markets and issuers. The adviser will decide how much to invest in the securities of a particular country or currency by evaluating the yield and potential growth of an investment, as well as the relationship between the currency and the U.S. dollar. The adviser may increase or decrease the emphasis on a type of security, sector, country or currency, based on its analysis of a variety of economic factors, including fundamental economic strength, earnings growth, quality of management, sector growth, credit quality and interest rate trends. The Fund may purchase securities where the issuer is located in one country but the security is denominated in the currency of another.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Geographic Focus Risk. The Fund may focus its investments in a region or small group of countries. As a result, the Fund’s performance may be subject to greater volatility than a more geographically diversified fund.

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

To the extent that the Fund hedges its currency exposure into the U.S. dollar, it may reduce the effects of currency fluctuations. The Fund may also hedge from one foreign currency to another. However, the Fund does not typically use this strategy for its emerging markets currency exposure.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Morgan Stanley Capital International (MSCI), Europe, Australasia and Far East (EAFE) Index (net of foreign withholding taxes) and the Lipper International Large-Cap Core Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance of Class C Shares is based on the performance of Class B Shares prior to the inception of Class C Shares. The actual returns of Class C Shares would have been similar to those shown because they have similar expenses to Class B Shares. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

SELECT CLASS SHARES	163	980	1,815	3,985

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 45% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal market conditions, the Fund will invest at least 80% of the value of its Assets in equity securities of Indian companies or instruments that have similar economic characteristics. “Assets” means net assets, plus the amount of borrowings for investment purposes. An Indian company is any company: that is organized under the laws of, or has a principal office in India; the principal securities market for which is India; that derives at least 50% of its total revenues or profits from goods that are produced or sold, investments made, or services performed in India; or at least 50% of the assets of which are located in India.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest. The Fund may from time to time hedge a portion of its foreign currency exposure into the U.S. dollar. The Fund is not constrained by capitalization or style limits.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: The Fund is managed by the sub-adviser using an active style of portfolio management which focuses on stock selection conducted by experienced country specialists. The subadviser employs a dedicated team of India specialists, located both within and outside India.

In managing the Fund, the sub-adviser seeks to add value primarily through stock selection decisions. In evaluating investment opportunities, the sub-adviser considers several criteria, including growth prospects, valuation, productive use of capital, competitive positioning, and corporate governance.

Indian country specialists are encouraged to visit a wide range of companies across a variety of sectors, and it is from these company visits that the sub-adviser can make qualitative assessments of the relative growth prospects of the companies concerned and their strategies to create shareholder value. The sub-adviser analyzes industries in which companies operate, the competitive landscape as well as the management strategy to enhance competitive advantage and returns. As part of the investment process, the country specialists not only meet with some of the companies which fall outside their core stock coverage, but they also meet with some of their competitors, distributors, suppliers and other stakeholders in order to obtain a complete analysis of the industry/company and other investment opportunities.

The portfolio managers are responsible for implementing the recommendations of the country specialists, who make their recommendations based on their extensive research. The sub-adviser prefers to construct a concentrated portfolio, thereby facilitating greater knowledge of the underlying holdings. The Fund also has access to the adviser’s team of global fund managers who may add insight at the sectoral, economic or other levels.

The Fund will sell securities if the sub-adviser believes the issuer of such securities no longer meets certain growth criteria, if certain political and economic events occur, or if it believes that more attractive opportunities are available.

The Fund is non-diversified.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Indian Market Risk. Investments in India can be considered speculative, and therefore may offer higher potential for losses. Political and economic structures in India generally lack the social, political and economic stability of more developed nations. Share prices of Indian companies tend to be volatile, can be subject to currency exchange fluctuations and can lack liquidity. The stock markets in India are undergoing a period of growth and change, which may result in trading or price volatility and difficulties in the settlement and recording of transactions, and in interpreting and applying the relevant laws and regulations. The risk of loss may be increased because Indian issuers are not subject to the extensive accounting, auditing and financial reporting standards and practices which are applicable in the United States. There is also a lower level of regulation and monitoring of the Indian securities market and its participants than in other more developed markets.

Because the Fund concentrates in a single region of the world, the Fund’s performance may be more volatile than that of a fund that invests globally. If Indian securities fall out of favor, it may cause the Fund to underperform funds that do not concentrate in a single region of the world.

Smaller Cap Company Risk. Investments in securities of smaller companies may be riskier and more volatile and vulnerable to economic, market and industry changes than securities of larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

Non-Diversified Fund Risk. Since the Fund is nondiversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased concentration in fewer issuers may result in the Fund’s shares being more sensitive to economic results of those issuing the securities.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past five calendar years. The table shows the average annual total returns over the past one year, five years and the life of the Fund. The table compares the performance to the Morgan Stanley Capital International (MSCI) India Index (net of foreign withholding taxes) and the Lipper India Region Funds Average, an average based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper average includes the expenses of the mutual funds included in the average. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund’s assets are invested primarily in equity securities of companies from developed countries other than the United States. The Fund’s assets may also be invested to a limited extent in emerging markets issuers. Developed countries include Australia, Canada, Japan, New Zealand, Hong Kong, Singapore, the United Kingdom, and most of the countries of Western Europe; emerging markets include most other countries in the world.

The equity securities in which the Fund may invest include, but are not limited to, common stock, preferred stock, convertible securities, trust or partnership interests, depositary receipts, privately placed securities and warrants and rights.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest.

The Fund will invest substantially in securities denominated in foreign currencies and may seek to manage currency risk where appropriate through managing currency exposure.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser employs a three-step process that combines research, valuation and securities selection.

The adviser selects securities for the Fund’s portfolio using its own investment process to determine which companies it believes are most likely to provide high total return to shareholders. The adviser chooses the most attractive securities in each sector and builds the portfolio bottom up. Securities in each industry are ranked with the help of fundamental valuations, then selected for investment. The adviser may adjust currency exposure to manage risks and enhance returns.

Through its extensive global equity research and analytical systems, the adviser seeks to generate an information advantage. Using fundamental analysis, the adviser develops proprietary research, primarily on companies but also on countries and currencies. In these processes, the analysts focus on a relatively long period rather than on near-term expectations alone.

Fundamental stock research is used to produce a ranking of companies in each industry group according to their relative value. The Fund’s adviser then buys and sells securities, using the research and valuation rankings as well as its assessment of other factors, including:

• catalysts that could trigger a change in a security’s price;
• potential reward compared to potential risk; and
• temporary mispricings caused by market overreactions.

The Fund may invest a substantial part of its assets in just one region or country.

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Morgan Stanley Capital International (MSCI), Europe, Australasia and Far East (EAFE) Index (net of foreign withholding taxes) and the Lipper International Large-Cap Core Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance of Class C Shares is based on the performance of Class B Shares prior to the inception of Class C Shares. The actual returns of Class C Shares would have been similar to those shown because they have similar expenses to Class B Shares. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 5% of the average value of its portfolio.

Strategy [Heading]

rr_StrategyHeading

What are the Fund’s main investment strategies?

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

Under normal conditions, the Fund will invest at least 80% of the value of its Assets in equity investments. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund will primarily invest in foreign companies of various market capitalizations , including foreign subsidiaries of U.S. companies.

The equity securities in which the Fund may invest include, but are not limited to, common stock, preferred stock, convertible securities, trust or partnership interests, depositary receipts and warrants and rights.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest.

The Fund may utilize currency forwards to manage currency exposure of its foreign investments relative to its benchmark. The Fund may also use exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser will seek to help manage risk in the Fund’s portfolio by investing in issuers in at least three different countries other than the United States. However, the Fund may invest a substantial part of its assets in just one region or country.

The Fund intends to invest in companies (or governments) in the following countries or regions: the Far East (including Japan, Hong Kong, Singapore and Malaysia), Western Europe (including the United Kingdom, Germany, the Netherlands, France, Switzerland, Italy, Scandinavia and Spain), Australia, Canada and other countries or areas that the adviser may select from time to time. A substantial part of the Fund’s assets may be invested in U.S. companies based in countries that are represented in the Morgan Stanley Capital International (MSCI), Europe, Australasia and Far East (EAFE) Index. However, the Fund may also invest in companies or governments in emerging markets.

The adviser may adjust the Fund’s exposure to each currency based on its view of the markets and issuers. The adviser will decide how much to invest in the securities of a particular country or currency by evaluating the yield and potential growth of an investment, as well as the relationship between the currency and the U.S. dollar. The adviser may increase or decrease the emphasis on a type of security, sector, country or currency, based on its analysis of a variety of economic factors, including fundamental economic strength, earnings growth, quality of management, sector growth, credit quality and interest rate trends. The Fund may purchase securities where the issuer is located in one country but the security is denominated in the currency of another.

Risk [Heading]

rr_RiskHeading

The Fund’s Main Investment Risks

Risk Narrative [Text Block]

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Geographic Focus Risk. The Fund may focus its investments in a region or small group of countries. As a result, the Fund’s performance may be subject to greater volatility than a more geographically diversified fund.

Derivatives Risk. Derivatives, including forward currency contracts and futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

To the extent that the Fund hedges its currency exposure into the U.S. dollar, it may reduce the effects of currency fluctuations. The Fund may also hedge from one foreign currency to another. However, the Fund does not typically use this strategy for its emerging markets currency exposure.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Performance Narrative [Text Block]

rr_PerformanceNarrativeTextBlock

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Select Class Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Morgan Stanley Capital International (MSCI), Europe, Australasia and Far East (EAFE) Index (net of foreign withholding taxes) and the Lipper International Large-Cap Core Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. The performance of Class C Shares is based on the performance of Class B Shares prior to the inception of Class C Shares. The actual returns of Class C Shares would have been similar to those shown because they have similar expenses to Class B Shares. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the table through 2/28/14 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

IF YOU SELL YOUR SHARES, YOUR COST WOULD BE:

Expense Example A, C, Select Shares JPMorgan Emerging Economies Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	679	1,035	1,415	2,477
CLASS C SHARES	313	693	1,200	2,592

CLASS C SHARES	213	693	1,200	2,592
SELECT CLASS SHARES	137	462	809	1,788

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 72% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal circumstances, the Fund invests at least 80% of the value of its Assets in equity securities of emerging markets companies and other investments that are tied economically to emerging markets. “Assets” means net assets, plus the amount of borrowings for investment purposes. Emerging markets include most countries in the world except Australia, Canada, Japan, New Zealand, Hong Kong, the United Kingdom, the United States, and most of the countries of Western Europe. An emerging market company is one: that is organized under the laws of, or has a principal place of business in an emerging market; where the principal securities market is in an emerging market; that derives at least 50% of its total revenues or profits from goods that are produced or sold, investments made, or services performed in an emerging market; or at least 50% of the assets of which are located in an emerging market.

The Fund is not required to allocate its investments in any set percentages in any particular countries. The Fund is not constrained by capitalization or style limits and will invest across sectors. The Fund will invest in securities across all market capitalizations, although the Fund may invest a significant portion of its assets in companies of any one particular market capitalization category.

The Fund may overweight or underweight countries relative to its benchmark, the Morgan Stanley Capital International (MSCI) Emerging Markets (EM) Index (net of foreign withholding taxes). The Fund emphasizes securities that are ranked as undervalued, while underweighting or avoiding securities that appear overvalued.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest. The Fund typically maintains full currency exposure to those markets in which it invests. However, the Fund may hedge a portion of its foreign currency exposure into the U.S. dollar.

The Fund may utilize currency forwards to reduce currency deviations, where practical, for the purpose of risk management. The Fund may use exchange-traded futures for the efficient management of cash flows. The Fund may also use participation notes in the management of portfolio assets.

Investment Process: The adviser believes that emerging markets are generally inefficient as demonstrated by the high and variable volatility of many emerging markets and individual companies in these markets. Corporate disclosure and transparency can vary widely thereby exacerbating the inefficiency of these markets and offering opportunities to experienced, well-informed active investors.

In managing the Fund, the adviser adheres to a disciplined process for stock selection and portfolio construction. A proprietary multi-factor model is used to quantitatively rank securities in the Fund’s investment universe which the adviser uses to select securities. Securities held in the Fund that the adviser believes have become over-valued and/or whose factor signals have deteriorated materially may be sold and are generally replaced with more attractive securities, on the basis of the adviser’s disciplined investment process.

The portfolio construction process controls for country and sector weights, number of stocks held, and position size. Risk or factor exposures are actively managed through portfolio construction.

The Fund has access to the adviser’s currency specialists in determining the extent and nature of the Fund’s exposure to various foreign currencies.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser's expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company's financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund's portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund's securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment’” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Smaller Cap Company Risk. Investments in securities of smaller companies may be riskier and more volatile and vulnerable to economic, market and industry changes than securities of larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivatives Risk. Derivatives, including forward currency contracts, futures and participation notes may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Preferred Stock Risk. Preferred stock generally has a preference as to dividends and liquidation over an issuer’s common stock but ranks junior to debt securities in an issuer’s capital structure. Unlike interest payments on debt securities, preferred stock dividends are payable only if declared by the issuer’s board of directors. Preferred stock also may be subject to optional or mandatory redemption provisions.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

High Portfolio Turnover Risk. The Fund will likely engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past four calendar years. The table shows the average annual total returns over the past one year and the life of the Fund. The table compares that performance to the Morgan Stanley Capital International (MSCI) Emerging Markets (EM) Index (net of foreign withholding taxes), and the Lipper Emerging Markets Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111. The performance figures in the bar chart do not reflect any deduction for the front-end sales charge which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 297% of the average value of its portfolio.

What are the Fund’s main investment strategies?

The Fund invests primarily in equity securities issued by companies with principal business activities in Western Europe. Under normal market conditions, the Fund invests at least 80% of the value of its Assets in equity securities of European issuers. “Assets” means net assets, plus the amount of borrowings for investment purposes.

The Fund may utilize exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser uses a bottom-up stock selection process that focuses on the value, quality and momentum characteristics to decide which stocks to buy and sell.

The Fund may invest in Austria, Belgium, Denmark, Germany, Finland, France, Greece, Ireland, Italy, Luxembourg, the Nether-lands, Norway, Portugal, Spain, Sweden, Switzerland, and the United Kingdom, as well as other Western European countries which the adviser believes are appropriate. In addition, the Fund may invest up to 8% of its Assets in equity securities of emerging market European issuers. These countries may include Poland, the Czech Republic, Hungary and other countries with similar economic profiles which the adviser believes are appropriate.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest. The adviser may adjust the Fund’s exposure to each currency based on its view of the markets and issuers. It may increase or decrease the emphasis on a type of security, sector, country or currency, based on its analysis of a variety of economic factors, including fundamental economic strength, earnings growth, quality of management, sector growth, credit quality and interest rate trends. The Fund may purchase securities where the issuer is located in one country but the security is denominated in the currency of another.

While the Fund’s assets will usually be invested in a number of different Western European countries, the Fund may at times invest most or all of the assets in a limited number of these countries. The Fund will, however, try to choose a wide range of industries and companies of varying sizes.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

European Market Risk. The Fund’s performance will be affected by political, social and economic conditions in Europe, such as growth of the economic output (the gross national product), the rate of inflation, the rate at which capital is reinvested into European economies, the resource self-sufficiency of European countries and interest and monetary exchange rates between European countries. European financial markets may experience volatility due to concerns about high government debt levels, credit rating downgrades, the future of the euro as a common currency, possible restructuring of government debt and other government measures responding to those concerns. In addition, if one or more countries were to abandon the use of the euro as a currency, the value of investments tied to those countries or the euro could decline significantly and unpredictably.

Derivatives Risk. Derivatives, including futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

High Portfolio Turnover Risk. The Fund will likely engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past ten calendar years. The table shows the average annual total returns over the past one year, five years and ten years. The table compares that performance to the Morgan Stanley Capital International (MSCI) Europe Index (net of foreign withholding taxes) and the Lipper European Region Funds Index, an index based on the total returns of certain mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper index includes the expenses of the mutual funds included in the index. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111. The performance figures in the bar chart do not reflect any deduction for the front-end sales charge, which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 41% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal market conditions, the Fund will invest at least 80% of the value of its Assets in equity securities of Russian companies or instruments that have similar economic  characteristics. “Assets” means net assets, plus the amount of borrowings for investment purposes. The Fund may, to a lesser extent, invest in equity securities of companies in the former Soviet Union countries other than Russia, or instruments that have similar economic characteristics. A Russian company is any company: that is organized under the laws of, or has a principal office in Russia; the principal securities market for which is Russia; that derives at least 50% of its total revenues or profits from goods that are produced or sold, investments made, or services performed in Russia; or at least 50% of the assets of which are located in Russia.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest. The Fund may from time to time hedge a portion of its foreign currency exposure into the U.S. dollar.

Investment Process: In managing the Fund, the adviser will use an active style of portfolio management which focuses on bottom-up stock selection conducted by experienced country specialists.

In managing the Fund, the adviser seeks to add value primarily through stock selection decisions. The adviser places a strong emphasis on bottom-up stock research conducted by country specialists. Macro research is used as a framework for this bottom-up analysis. The investment process is characterized by identifying and purchasing securities issued by high quality companies with sustainable earnings growth on attractive valuations, and avoiding overvalued stocks and markets. The adviser prefers to construct a concentrated portfolio, thereby facilitating greater knowledge of the underlying holdings.

The Fund will sell securities if the adviser believes the issuer of such securities no longer meets certain growth criteria, if certain political and economic events occur, or if the adviser believes that more attractive opportunities are available.

The Fund is non-diversified.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Russian Market Risk. Investing in Russian securities is highly speculative and involves significant risks and special considerations. Since the breakup of the Soviet Union in 1991, Russia continues to experience dramatic political and social change. Though Russia has been transitioning from a centrally controlled command system to a more market-oriented democratic model, recent political developments have trended back to high government involvement and centralized control in some industries, such as Russia’s oil and gas industries. The Russian securities markets are substantially smaller, less liquid and more volatile than the securities markets in the U.S., with a few issuers representing a large percentage of market capitalization and trading volume.

The Fund may be affected unfavorably by political developments, social instability, changes in government policies, and other political and economic developments. There is the potential for expropriation, dilution, devaluation, default or excessive taxation by the Russian government or any of its agencies or political subdivisions with respect to investments in Russian securities by or for the benefit of foreign entities. The Russian economy is heavily dependent upon the export of commodities  including most industrial metals, forestry products, oil and gas. Accordingly, it is strongly affected by international commodity prices and global demand for these products. Furthermore, it is possible that the Fund’s ownership rights could be lost through fraud or negligence because ownership of shares in Russian companies is recorded by the companies themselves and by registrars instead of through a central registration system. Since the Russian banking institutions and registrars are not guaranteed by the state, the Fund may not be able to pursue claims on behalf of the Fund’s shareholders.

Because the Fund concentrates in a single region of the world, the Fund’s performance may be more volatile than that of a fund that invests globally. If Russian securities fall out of favor, it may cause the Fund to underperform funds that do not concentrate in a single region of the world.

Smaller Cap Company Risk. Investments in securities of smaller companies may be riskier and more volatile and vulnerable to economic, market and industry changes than securities of larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

Derivatives Risk. Derivatives may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Non-Diversified Fund Risk. Since the Fund is nondiversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased concentration in fewer issuers may result in the Fund’s shares being more sensitive to economic results of those issuing the securities.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Strategy Narrative [Text Block]

rr_StrategyNarrativeTextBlock

The Fund invests primarily in equity securities issued by companies with principal business activities in Western Europe. Under normal market conditions, the Fund invests at least 80% of the value of its Assets in equity securities of European issuers. “Assets” means net assets, plus the amount of borrowings for investment purposes.

The Fund may utilize exchange-traded futures for the efficient management of cash flows.

Investment Process: In managing the Fund, the adviser uses a bottom-up stock selection process that focuses on the value, quality and momentum characteristics to decide which stocks to buy and sell.

The Fund may invest in Austria, Belgium, Denmark, Germany, Finland, France, Greece, Ireland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, and the United Kingdom, as well as other Western European countries which the adviser believes are appropriate. In addition, the Fund may invest up to 8% of its Assets in equity securities of emerging market European issuers. These countries may include Poland, the Czech Republic, Hungary and other countries with similar economic profiles which the adviser believes are appropriate.

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest. The adviser may adjust the Fund’s exposure to each currency based on its view of the markets and issuers. It may increase or decrease the emphasis on a type of security, sector, country or currency, based on its analysis of a variety of economic factors, including fundamental economic strength, earnings growth, quality of management, sector growth, credit quality and interest rate trends. The Fund may purchase securities where the issuer is located in one country but the security is denominated in the currency of another.

While the Fund’s assets will usually be invested in a number of different Western European countries, the Fund may at times invest most or all of the assets in a limited number of these countries. The Fund will, however, try to choose a wide range of industries and companies of varying sizes.

rr_RiskNarrativeTextBlock

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

European Market Risk. The Fund’s performance will be affected by political, social and economic conditions in Europe, such as growth of the economic output (the gross national product), the rate of inflation, the rate at which capital is reinvested into European economies, the resource self-sufficiency of European countries and interest and monetary exchange rates between European countries. European financial markets may experience volatility due to concerns about high government debt levels, credit rating downgrades, the future of the euro as a common currency, possible restructuring of government debt and other government measures responding to those concerns. In addition, if one or more countries were to abandon the use of the euro as a currency, the value of investments tied to those countries or the euro could decline significantly and unpredictably.

Derivatives Risk. Derivatives, including futures, may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

High Portfolio Turnover Risk. The Fund will likely engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are equal to the total annual fund operating expenses after fee waivers and expense reimbursements shown in the table through 2/28/14 and total annual fund operating expenses thereafter. Your actual costs may be higher or lower.

IF YOU SELL YOUR SHARES, YOUR COST WOULD BE:

Expense Example A, C, Select Shares JPMorgan Latin America Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	689	1,088	1,512	2,689
CLASS C SHARES	323	746	1,295	2,795
SELECT CLASS SHARES	148	518	912	2,018

IF YOU DO NOT SELL YOUR SHARES, YOUR COST
WOULD BE:

Expense Example, No Redemption A, C, Select Shares JPMorgan Latin America Fund (USD $)	1 Year	3 Years	5 Years	10 Years
CLASS A SHARES	689	1,088	1,512	2,689
CLASS C SHARES	223	746	1,295	2,795
SELECT CLASS SHARES	148	518	912	2,018

Portfolio Turnover

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund’s performance. During the Fund’s most recent fiscal year, the Fund’s portfolio turnover rate was 49% of the average value of its portfolio.

What are the Fund’s main investment strategies?

Under normal market conditions, the Fund will invest at least 80% of the value of its Assets in securities of Latin American issuers and other investments that are tied economically to Latin America. “Assets” means net assets, plus the amount of borrowings for investment purposes. Latin America includes, but is not limited to, Argentina, Brazil, Chile, Colombia, Ecuador, Guatemala, Mexico, Peru, Panama and Venezuela. The Fund will invest primarily in foreign companies of various sizes, including foreign subsidiaries of U.S. companies.

The Fund’s adviser considers a number of factors to determine whether an investment is tied economically to Latin America including: the source of government guarantees (if any); the primary trading market; the issuer’s domicile, sources of revenue, and location of assets; whether the investment is included in an index representative of a particular country in Latin America or the Latin American region; and whether the investment is exposed to the economic fortunes and risks of a particular country in Latin America or the Latin American region.

The Fund may overweight or underweight countries relative to its benchmark, the Morgan Stanley Capital International (MSCI) Emerging Markets (EM) Latin America Index (net of foreign withholding taxes).

The Fund may invest in securities denominated in U.S. dollars, major reserve currencies and currencies of other countries in which it can invest. The Fund may from time to time hedge a portion of its foreign currency exposure into the U.S. dollar.

Investment Process: The adviser focuses on active and fundamental research, relying less on published data and more on subjective analysis conducted primarily through company visits by locally-based country specialists.

In managing the Fund, the adviser seeks to add value primarily through stock selection decisions. Thus, decisions about country weightings are secondary to those about the individual stocks, which make up the portfolio. The portfolio manager is primarily responsible for implementing the recommendations of our country specialists, who make their recommendations based on the stock ranking system.

The primary emphasis in selecting securities for the Fund is on bottom-up stock research conducted by country specialists, while macro research is used as a framework for the analysis.

The Fund will sell securities if the adviser believes the issuer of such securities no longer meets certain growth criteria, if certain political and economic events occur, or if it believes that more attractive opportunities are available.

The Fund is non-diversified.

The Fund’s Main Investment Risks

The Fund is subject to management risk and may not achieve its objective if the adviser’s expectations regarding particular securities or markets are not met.

An investment in this Fund or any other fund may not provide a complete investment program. The suitability of an investment in the Fund should be considered based on the investment objective, strategies and risks described in this prospectus, considered in light of all of the other investments in your portfolio, as well as your risk tolerance, financial goals and time horizons. You may want to consult with a financial advisor to determine if this Fund is suitable for you.

Equity Market Risk. The price of equity securities may rise or fall because of changes in the broad market or changes in a company’s financial condition, sometimes rapidly or unpredictably. These price movements may result from factors affecting individual companies, sectors or industries selected for the Fund’s portfolio or the securities market as a whole, such as changes in economic or political conditions. When the value of the Fund’s securities goes down, your investment in the Fund decreases in value.

General Market Risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions.

Foreign Securities and Emerging Market Risks. Investments in foreign issuers and foreign securities (including depositary receipts) are subject to additional risks, including political and economic risks, civil conflicts and war, greater volatility, expropriation and nationalization risks, currency fluctuations, higher transaction costs, delayed settlement, possible foreign controls on investment, and less stringent investor protection and disclosure standards of foreign markets. In certain markets where securities and other instruments are not traded “delivery versus payment,” the Fund may not receive timely payment for securities or other instruments it has delivered and may be subject to increased risk that the counterparty will fail to make payments when due or default completely. Events and evolving conditions in certain economies or markets may alter the risks associated with investments tied to countries or regions that historically were perceived as comparatively stable becoming riskier and more volatile. These risks are magnified in “emerging markets.”

Latin American Market Risk. The economies of countries in Latin America are all considered emerging market economies. High interest, inflation (in some cases substantial and prolonged), and unemployment rates generally characterize each economy. Because commodities such as agricultural products, minerals, and metals represent a significant percentage of exports of many Latin American countries, the economies of those countries are particularly sensitive to fluctuations in commodity prices. Investments in the region may also be subject to currency risks, such as restrictions on the flow of money in and out of the country, extreme volatility relative to the U.S. dollar, and devaluation, all of which could decrease the value of the Fund.

Governments of many Latin American countries exercise substantial influence over many aspects of the private sector, and any such exercise could have a significant effect on companies in which the Fund invests. Other Latin American market risks include foreign exchange controls, difficulties in pricing securities, defaults on sovereign debt, difficulties in enforcing favorable legal judgments in local courts and political and social instability.

Because the Fund concentrates in a single region of the world, the Fund’s performance may be more volatile than that of a fund that invests globally. If Latin American securities fall out of favor, it may cause the Fund to underperform funds that do not concentrate in a single region of the world.

Smaller Cap Company Risk. Investments in securities of smaller companies may be riskier and more volatile and vulnerable to economic, market and industry changes than securities of larger, more established companies. As a result, share price changes may be more sudden or erratic than the prices of other equity securities, especially over the short term.

Derivatives Risk. Derivatives may be riskier than other types of investments because they may be more sensitive to changes in economic or market conditions than other types of investments and could result in losses that significantly exceed the Fund’s original investment. Many derivatives create leverage thereby causing the Fund to be more volatile than it would be if it had not used derivatives. Derivatives also expose the Fund to counterparty risk (the risk that the derivative counterparty will not fulfill its contractual obligations), including credit risk of the derivative counterparty. Certain derivatives are synthetic instruments that attempt to replicate the performance of certain reference assets. With regard to such derivatives, the Fund does not have a claim on the reference assets and is subject to enhanced counterparty risk.

Currency Risk. Changes in foreign currency exchange rates will affect the value of the Fund’s securities and the price of the Fund’s shares. Generally, when the value of the U.S. dollar rises in value relative to a foreign currency, an investment in that country loses value because that currency is worth fewer U.S. dollars. Devaluation of a currency by a country’s government or banking authority also will have a significant impact on the value of any investments denominated in that currency. Currency markets generally are not as regulated as securities markets.

Non-Diversified Fund Risk. Since the Fund is nondiversified, it may invest a greater percentage of its assets in a particular issuer or group of issuers than a diversified fund would. This increased concentration in fewer issuers may result in the Fund’s shares being more sensitive to economic results of those issuing the securities.

High Portfolio Turnover Risk. The Fund will likely engage in active and frequent trading leading to increased portfolio turnover, higher transaction costs, and the possibility of increased capital gains, including short-term capital gains that will generally be taxable to shareholders as ordinary income.

Redemption Risk. The Fund could experience a loss when selling securities to meet redemption requests by shareholders. The risk of loss increases if the redemption requests are unusually large or frequent, occur in times of overall market turmoil or declining prices for the securities sold, or when the securities the Fund wishes to or is required to sell are illiquid.

Investments in the Fund are not deposits or obligations of, or guaranteed or endorsed by, any bank and are not insured or guaranteed by the FDIC, the Federal Reserve Board or any other government agency.

You could lose money investing in the Fund.

The Fund’s Past Performance

This section provides some indication of the risks of investing in the Fund. The bar chart shows how the performance of the Fund’s Class A Shares has varied from year to year for the past five calendar years. The table shows the average annual total returns over the past one year, five years and the life of the Fund. The table compares that performance to the Morgan Stanley Capital International (MSCI) Emerging Markets (EM) Latin America Index (net of foreign withholding taxes) and the Lipper Latin American Funds Average, an average based on the total returns of all mutual funds within the Fund’s designated category as determined by Lipper. Unlike the other index, the Lipper average includes the expenses of the mutual funds included in the average. Past performance (before and after taxes) is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available by visiting www.jpmorganfunds.com or by calling 1-800-480-4111. The performance figures in the bar chart do not reflect any deduction for the front-end sales charge, which is assessed on Class A Shares. If the sales charge were reflected, the performance figures would have been lower.
